Hah! Perfect

At one time (when I was 19... how did that happen? Oh, yeah; straw purchase) I had a 7-1/4" barrel Ruger Super Redhawk in .44mag with a scope.

Practical? Well, not for self defense; but... fun? Hell yes

I myself had the nickname "Crash" (they made me a nametag that said that) when I was waaay early in my career, not mandated yet, and backed the Escort Van into a parked car

We had a saying: "If no one teases you, then they don't like you"

We had an officer named "Nozzle" because he drove away from the gas pump with the pump nozzle still in the fuel port. Broke the hose and dented the side of the crown vic.

A deputy named "Juicy" because... well... poor guy had hyperhydrosis and sweated a lot.

a *lot*

That's not a terribly bad grip for a revolver; which a lot of older deputies I instructed used because they were used to .38 police revolvers.

Heh, and nicknames have always been a thing across all genres.

It is a very self-correcting problem, though. ๐Ÿ˜†

I shot Creedmore position at long distances with a revolver before, and it always made me twitchy. Yikes.

Expand the photo and look at all the high speed fragments blasting past the shooter...

Yes, that's a H&K sling on an inch FN-FAL. That's how I roll.

You can see a little spurt of flame in the last photo at the cylinder gap... SP-101 has a pretty tight gap, but something always gets through.

Also that's not me shooting these guns; I was on the camera.

Long barrel of the FN-FAL let the powder burn almost completely; another shot of the .500, two of the SP-101 .357 with dirty ammo

This is the one I was thinking of. .500 S&W Magnum.

"Aaaah, S-23 to Central, is there another unit free? Train delay" was all you needed to say

Barrow County Ga, when I was a Deputy, had a set of moderately used tracks that split the county in two along its length. You'd be barrelling along code 3 to get to a call, hoping you could beat the train at the next intersection to get to the call north of the tracks.

I once did some second curtain sync nighttime flash photos of firearm muzzleflashes; and there were a disconcerting number of fragments and gas ejected from even a tight cylinder gap revolver.

BRB, gonna see what I can find in the archives

Don't think any jurisdiction I worked had Opticom; but the trick to make sure the camera saw you for something like a motorcycle is helpful. Spent way too much time in the early days stuck at a light because it didn't sense the bike.

How Traffic Lights Work! YouTube video by Traffic Light Doctor

At 5:01, there's an explainer about how the myth of flashing your headlights at a red light will cause it turn green (Opticom preemption for emergency vehicles) is wrong; buuuut how modern traffic signals use cameras to gauge lane occupancy and how it *might* help at night in a dark vehicle.

I really wish I had thought of this as a demo when I was an instructor. But the instances of deputies cutting railroad tracks into their thumb also worked to drive home the point.

Did yโ€™all ever do the kill switch slap just before the red light turned green? Slapping this switch and riding away while the other guy had to restart his bike?

The billionaires finally have the complacent-because-no-one-told-them-to-think-critically voter base/workforce they've always wanted

She should, IMO... or, better yet, sue whoever created this situation; although they're probably part of the school district.

Readin', Ritin', and 'Rithmetic... and especially critical thinking, and learning HOW to think and solve problems... has taken quite a beating... for a lot of reasons

Heh... The guy that taught me how to ride, and whose only means of transportation for years and years was a bike, did that in front of a grocery store. Picked his feet up and slowly fell over into a bush ๐Ÿคฃ

Heard a helicopter outside but couldn't see it, so fired up the ADS-B. Looks like Army Reserve is doing some training:

Although, I can see where that might be useful for folks with limited mobility and might not be able to use foot controls.

Thank you.

...It sounds kind of shitty to say, but...

His death affected me more than my parents.

Although those were... expected, I guess.

I don't think that bike had so much hidden snoot, but...

...Yeah, I wanted that bike when I saw the movie.

Also wanted those Kawaski KZ-1000s from Mad Max when I first saw it, long before I was old enough to ride one

The county DA at the time can get get fucked for all I care. "Oh, he's young, he shouldn't have to have this hanging over his future"

He killed someone. Fuck him; he should think on this for the rest of his life.

Thank you, ACCPD traffic guys, for charging appropriately. I would have done the same
