In the present as well as the past we've noticed multiple gang members spawning as a cop in order to bypass the 10-cop requirement for starting a bank robbery. This should not be allowed for obvious reasons.
A simple fix to this is for validation of whether or not a person is in a gang, and thereby deciding whether or not to count them towards the 10-cop limit script.
Current script should be relying on the current amount of cops. If there are 10 cops on as the bank robbery spawns, it shouldn't "deactivate" the ability to crack if they despawn. I agree with that.
