Because they just don't give a crap. Some criminals who stragically plan out a crime will not and these are people that are still out there. They don't get caught and they don't want to get caught which means no evidence and sometimes no witnesses. But someone that wants to rob a grocery/liquor store at closing just for some quick cash will. These type of people IMO don't care about the consequences, they don't care who they hurt or why.
