Gunshots heard all around HPP lastnight

[whalesong]

I am no expert on guns. All I know, it was quick loud rapid fire. I felt each shoot, as I heard them and then, I called to report it. I was afraid, at the time, no one else was at home.
I was told, I should make a report with the FBI and Alcohol Tobacco and Fire Arms Dept.
I would think, that the police would have already done this, since this is not the first time.
The other thing, I'd like to mention, is that, there is a person living on our road, who drives a Red ATV, he was returning home last night at 11 a.m. Why would anyone be out, at that time of night, if they were not out scoping out homes to rob and calling them in to someone else in a vehicle. In my opinion, I think he is part of the burglaries going on around here. This fellow lives only two lot over from the house that was burglarized on Friday and the puppy was stolen. He would know when she leaves. I informed her/and Jerry of my suspicions.
Jerry informed me to call the non-emergency # and make a report, when I see him out, which I will. ATV are illegal to ride in the park.
This is a serious issue and we all have to work together to end it and get these psycho's out of our neighborhood and locked up.
By the way, if I'd heard someone screaming before the shots, I would have called 911 for assistance for that person.

Be safe, Be Alert- Remember to Carry your cell phone and maze with you at all times. You never know these days, when you will need them. I walk my dog everyday, and I don't leave home without them.
Mahalo for sharing this concern, Kololia

I can think of lots of reasons why someone would be returning home at 11, they could have been visiting friends in HPP and been coming home to go to bed. I normally go to bed at 9, but not everyone does, and on my poker night we are out until late. I would hate to think that my neighbors are assuming I am a criminal if I stay out late sometimes. I would be very careful about jumping to the conclusion that someone is a criminal just because they are out at night. If you have other supporting evidence you didn't state it here.

It is good to be alert and observe what is going on around you and taking note if it seems unusual. That said I rarely am in bed before 1:00AM and have been seen jogging in the cooler evening air after 10PM. I may be suspect to some but I am not up to anything so I am not overly concerned with what they think. ;-)

1) backfire in an automotive engine caused by early ignition timing will give a pop,pop,pop. Can sound just like automatic weapon when the gas is released ...

2) see mythbusters about returning bullets .... if fired in the air... they will not land with the same force or enough impact to do real harm


hope it was car exhaust... Jerry has enough of a workload

from mythbusters:
9mm 4,000 ft, 37 seconds
Terminal velocity of a falling bullet

Adam built an acrylic wind tunnel (much like the one in the Penny Drop myth). Air was shot up through the bottom and a bullet was dropped into the chamber. The terminal velocity was calculated based on the speed of the air needed to make the bullet stop falling. They figured that the terminal velocity was 100mph (150 ft/s). The wind tunnel also showed that the most stable falling position for the bullets was on their side.

SkyDaver on Mythbusters examination of falling bullets:

They're testing the basic bullets in the air myth.

They're going to try to determine if a bullet, falling vertically at terminal velocity, can kill. I'll write comments as the show broadcasts.

They determined that a 9mm FMJ bullet falls at about 100mph (but it was tumbling)

A .30-06 was also at about 100 mph.

The stable falling position was wobbly, and sideways. Again, no spin though.

Then, they built a rig to shoot the bullets at the appropriate terminal velocity.

This, though, isn't going to have the bullet going sideways, but will be tip first.

Then, they fired these bullets into a pig skull, and determined that it was not lethal.

So far, they haven't addressed that the fired bullets are spinning (which will change the way the bullets fall), and they still don't have a clue that firing into the air does NOT equal firing straight up.

A bullet fired non-vertical will maintain its point first attitude during flight, and it's terminal velocity will not be as slow as a tumbling bullet.

Also, they have not addressed the fact that non-vertically fired bullet will keep some amount of its horizontal vector as well as the vertical vector.

It would be pretty difficult to measure the velocity of a bullet fired at 45 degrees, for example, at the end of its flight.

There are certainly cases where bullets fired from long distance are lethal.

Ah, finally, they got the clue that if a bullet hits someone from a great distance, then the bullet isn't going to lose so much velocity that it isn't potentially lethal.

Now, they're going to try literally firing bullets straight up.

They found two 9mm bullets, fired straight up, about 330 ft from the firing point (carried by the wind, obviously) The depth of penetration indicated that it was falling sideways when they hit. Still, these were fired straight up, not at any measurable angle. (added on edit) Obviously, they don't have any telemetry from the path, but even if the bullet is still spinning at apogee, it appears to start falling backwards, and losing stability, rather than nosing over.

They couldn't find any .30 cal bullets, fired from a Garand.

Then, they lofted a bunch of bullets with a balloon to about 400 feet, and dropped them. Sure enough, the .30 cal bullets at unstable terminal velocity were non-lethal. They did a good job of calculating that bullets falling vertically were non-lethal.

They closed by emphasising that it is almost impossible to fire straight up, and if you've got any angle at all, the bullet will maintain its nose first attitude, and WILL be coming to earth at lethal velocity. They also emphasised that one should NEVER fire a firearm into the air...

They also emphasized that one should NEVER fire a firearm into the air... and I'd add, especially not at night, in a residential neighborhood, with apparently malicious intent.

terminal velocity is terminal ... velocity ... sky divers (yup in a younger day) or bullets 120 is about as fast as things get. Now if we lived in a vacuum ..... Id wear a helmet - grin

Its another one of those basic laws of physics. (drag (resistance) increasing the square of velocity) We used to pass pumpkins in free fall at the halloween meets. Watched them impact at 120 mph when we were finished passing them back and forth- great fun

two things that fall from the sky --- fools and birdsh...


My money still being on backfires. .... Follows the logic of my first supervisor at the phone company technical center....
His mantra - always start with the simplest solution for a problem

I agree on the terminal velocity. I have seen the aftermath of New Years several times and the damage inflicted from a "falling" bullet is usually minimal. However, that's assuming it is fired straight up and the only velocity is the "terminal velocity". Unfortunately, there is a good chance that, if it was gunfire, it was not straight up, which gives it a large "effective" range. Any idiot that drives around randomly popping caps needs a long stay in jail.

Who was the comedian that said he believes everyone should have guns but bullets should cost $10,000 each? If you get popped with $10K bullets it probably was no accident.

Guys think out the problem.... the bullet runs out of energy at the apex of its travel... then reaches zero upward speed.. at the apex the bullet begins its descent. If typical it will be tumbling and much slower than 120 no matter what the initial upward angle

Doesn't matter what angle its fired at ...

Wikipedia: "And the same terminal velocity is reached for a typical 150 grain bullet travelling in the downward vertical direction — when it is returning to earth having been fired upwards, or perhaps just dropped from a tower — according to a 1920 U.S. Army Ordinance study"

back to skydiving analogy

When I leave the airplane Im moving forward at the aircraft speed.... my body slows slows as I exit and begins the descent..... by the time my forward speed bleeds off .... my descent being vertical. Speed never exceeding terminal velocity however. Unless I strap on a jet pack.

again basic physics - My money still being on backfiring as a source of the automatic gunshot sound

Wasn't it Galileo, way back when, who dropped two same-shape-and-size but different-mass items (such as a grapefruit and a cannonball) from the Leaning Tower of Piza and established the whole lore about gravity, terminal velocity, wind resistance (if a feather is dropped instead of a same-shape object) and so on? The validity of terminal velocity is unquestioned here. The rub is whether of not the bullets have actually reached an apex and so defaulted to coasting back down (an issue to which the angle of fire does matter, m'thinks, relative to the place the bullet hits). 'Tis moot though, really, when the natural experiment of idjits firing off guns has documentedly produced the result of people injured and killed.
