A map of the shooting

Wow. That's a huge fucking oversight.

Seriously how the fuck did the secret service fuck this up this bad
- Because he had to get rid of all the competent agents on his team, and is only left with the corrupt shitbags.
- Maybe they tried to deescalate the situation instead of shooting like usual?
- I imagine they aren't treated well by him. I'm not joking, or being facetious.
But guys the roof was slanted a tiny bit

venue does look like a step up from Four Seasons Landscaping

Does it have a dildo store?
- They don't need a dildo store, they had a dildo speaker.

oh shit. they got a mini golf. I miss mini golf.

I miss drive-in theaters

Kind of makes you wonder how many shootings get quietly thwarted. Not just "guy in a roof not allowed to bring gun" kind of situations but also "weirdo posts anti-trump stuff on Lemmy and isn't allowed to attend".

I know the kidnapping attempt on the governer was the latter and publicized but who knows if they let the media know about all of them. There's a lot of freaking people capable of this stuff in a country full of guns.

"weirdo posts pro-trumo stuff"

Question: As a non-American and therefore with no gun or weapon knowledge, what is the range of riffles or commonly available guns that one could buy off a regular gun shop?

He used an AR-15 which in theory is accurate to about 300m for a proficient shooter, but amateur shooters shouldn't really expect more than 100m. If he hadn't fallen for the marketing campaign he'd have just used a deer rifle and probably gotten the bastard for half the cost.
That all said, a lot of rifles have theoretical effective ranges that only apply to top marksmen, so anything would have worked if he'd had a steadier aim, but that's easier said than done.
- My basic training was with an M16A2 manufactured in the 80s and after a couple hours and ~100 rounds of practice I could group center with iron sights at 500y (457m) and that's functionally the same gun. Effective range for an AR-15 should be the same 600y(550m) as the old M16s from the 70s and 80s, extended to ~1000y (914m) with extra training, better sights, and a match grade rifle
The maximum effective range of an AR-15 is about 300m, but that's with training and patience. The average shooter would be happy to consistently hit a 100m target. The Internet will say 500+, but my experience is that it's not possible for the average person.
- He probably also aimed for the head, which is way smaller target than body, especially in this case. In military training was mainly to shoot to body, because it really doesn't matter in combat.
Depending on how the gun was configured/chambered, and weather conditions, I think it's quite hard. Also considering he probably only had shooting range experience, and was a kid under heavy stress.
Also not American, but at roughly the same age trained on the HK G3, which uses a bigger caliber and longer barrel, under simulated stress conditions could hit a target at about 400m reliably. After intensive training, and "hit a target" does not necessarily mean a headshot, but somewhere on the body. We were explicitly told to aim for the biggest mass, not fanciness.
I think that shooter was misguided in many ways, and also by advertising, as already mentioned in this thread.

The only way that guy got on the roof is if he was already familiar with the building. My guess is that he worked there at some point. You couldn't have gotten onto that property from the venue.

Edit Google maps got in the back lot somehow:

Easy climbing access from their west lot:

Well there ya go. You didn't even have to leave your couch to find an access point. No former employment needed.

Man this really was the dump assignment for the Secret Service's worst agents, wasn't it.
