Basically my suggestion is that if there is an active warrant for a character, an individual cannot stat-transfer that character's things to another character. It prevents MG as I've heard in the past players found out they have warrants and simply stat-transferred their shit and the entire purpose of the warrant or the entire purpose of the investigation was meaningless because said person can continue doing what they were doing basically without a problem. I believe it is a small change that does a lot in the long run.
The implementation is extremely easy (at least imo) as it is a rather simple conditional statement?
Let me know what you think, make your case for why this shouldn't happen, etc.
