while I do not agree with shoplifting and I do think that they are criminals, you have to be very carefull about the escalation of force. At the point in time that you called the police they were only "suspected" of commiting a crime. I realize that you may have seen and caught them red handed, but they are still innocent until proven guilty in a court of law. You have the right to detain them until the police come, but you are than taking the responsibility and possible legal ramifications of your actions. If you physicaly restrain them, they will than instinctivily physicaly resist, this is their right. If you show a weapon, they must believe that you will use it, if they believe that you will do them harm, they will resist this weapon too. They will than either run, or choose their own weapon. if you use a weapon on them, they will than be forced to use a weapon on you. Its simply a tit for tat ratcheting up of violence. I am not sure what your states rules are, but i am not really sure if you are allowed to tazer someome because you "suspect" that they "may" have "possibly" stolen from a store. I am also not sure if you are legaly entitled to tazer someone because they did follow your instructions to sit and wait. I guess if the police decide to deputize you, you would than be granted this authority, but untill you are explicitly invested with this power by the state or society you are not really allowed to engage in physical intercourse with any other person, criminal or not. I do not like shoplifters, and Iwould personaly forget about legality, right, wrong or otherwise if I cought a shoplifter in my store.....
