The demo system is always recording unless you have deleted them from the phdemos folder, which would be against server rules. Please check the guide provided by @Creepis.
When trying to gun-point people, you must make sure to give them enough time to react and follow your instructions. Given your 2.5 record, I will be issuing a ban, although I will be lenient considering how you have admitted to your wrongdoing.
It took about 13 minutes between your first death (at the very beginning of the raid) and your second one. Shootouts are known to last longer than 10 minutes in many cases, and you based your sole decision on that time being elapsed. You should have not responded if you had no other indication...
If you die as a civilian, you cannot return to the same shootout, not even when the NLR time is over, not even when you have switched jobs. Considering this, do you still believe the punishment is invalid?
Roadcrew workers are Government Employees. I still disagree with them getting a panic, though, as I feel like it makes more sense for them to have to use 911 calls.
