Again, you could never get a government job because your character is a murderer. It's not realistic. This is a matter of the characters role. They do have an identity. They have contacts who know them and hire them for help. It would make no sense if the government hired you.

Not everyone plays like you do, nor does everyone necessarily go on Cop-killing rampages. But that doesn't matter too much; there's already a lot of suspension of disbelief in Online, especially so with the cops. You can happily go on as many rampages as you like and, timer willing, give Lester a buzz to get the heat off your back.
