If such a programm will be made, wouldn't it make game crash more often?
Besides, if weapons are free, what can you loose?
BUT, if Ammunition idea will get accepted, this idea really should be done.
Conclusion : wouldn't these 2 BIG scripts make game crash like a hell? Then better don't change anything about it.
If it is necessary to get new notpolice ways to get money, im sure our imagination can work for it.
