People do get killed quite often in cases of mistaken identity. Not by the police, usually, but criminal gang wars are not without innocent victims. Criminals do get charged with theft from other criminals. The only benefit to stealing from criminals is that they won't go to the police, but that doesn't mean they won't report you once they get caught. They may even get out if jail earlier by coming clean and listing every criminal they've interacted with.
