conceal & carry insurance
In general, I think it's a good idea. People found not guilty can still have to shell out over $100k due to the fees associated with a legal and civil court battle. Also, just because you win the legal battle doesn't mean you will win in civil court.
Questions you want to ask before buying are
1 - When do they come to your aid?
2 -Will they pay for your lawyer up front or reimburse you for the cost after the trial?
3 - What are the limitations of the policy?
4 - Who decides if you qualify for the pay out?
There are three companies I would recommend researching are:
1 - Legal Defense Network. Massad Ayoob is a board member. If you carry a firearm for self defense and do not know who he is you should stop reading this and google him.
2 - USCCA. Wisconsin based company that supported carriers long before it was legal in Wisconsin
3 - NRA. Needs no introduction.
All three are reputable and would stand behind their products.
