Well there is plenty of examples of Cops in Gta sa without any logic let's be fair, this makes the game even more better!!! i love it. Anyway i'm gonna share a little info you may not know.

1) This cop CANNOT arrest you:
Yes you heard right! if you have 1-star wanted level and exit a building you will see an cop without it's nightstick this cop CANNOT arrest you.

2) Gun at Face (No Wanted level):
We all know pointing a gun (Such as pistol, SMG, etc.) Towards a cop triggers Wanted level and the officer shoots you with his pistol but pointing a MINIGUN towards an officer......well Nothing happens the officer just don't react at all. (Same as Sniper NO REACTION OR WANTED LEVEL)

Conclusion police in gta sa has pretty interesting logic do they?

What's your opinion in this?

Edit: Typos

Cool story bro

I would suggest posting this on e.g. GTAForums, as this is a forum about speedrunning rather than game trivia.

1)
Interesting, I thought the cop was created by the mission itself but I cannot find any sign of that.

2)
I suppose you play on console because I think you should get a wanted level with a minigun on PC. My line of thinking is: When you aim at someone, as on console, there is no health indicator (green/red thing telling you about health) for sniper rifles/etc. On PC, there is one for the minigun, on console there is not.

@Patrick_Patrick_ i'm playing on PC. Also i can copy that and posting on Trivia btw, thanks for telling me. Where i can find this forums?

2) The indicator appears normally but still the cop doesn't react. This one is perfect for Meming i just realize that. You know pointing a small 9mm in cop he shoots you, but pointing a huge ass Minigun... well yeah is normal for him LOL. Just a normal day in Gtasa.

Edit: i found another strange thing that triggers wanted level.

BMX shooting: Shooting a BMX or a mountain Bike(I didn't test this one but it should react the same) It gives you a little exp and then triggers a very light wanted level also the BMX stops giving you exp.
