this idea is little hard lets start
u make a cmd called !rob the criminal go to bank with guns he type !rob and in police radio show (there is a robbery in the bank robber User)
then the police go to there and tell him to sur if he sur the money will go if he ran away for 30min (or less time) the money will be for him and never go if he died the money will go.
thats my idea i hope u like it
