Good luck with that in court. I know by police reports and news articles, heck even cops has have more than a few, of many would be thieves who had rude surprises waiting on them after repeated breakins. Most juries do not support the criminals who breaks in and are injured in the process. I have seen many who were greeted by armed homeowners or business owners this is no different. Many of whom are rightly shot for their efforts. As for the "Topic" have fun with that too since constitutionally they could put whatever including mines on the border to protect the country.
