Periodically, I am asked to opine about the various plans available to cover the expenses of a legal defense after a personal protection incident. This article by Marty Hayes covers it in much better detail than I could explain.

The [plans] can be categorized into four types:
1) Insurance
2) Insurance backed
3) Pre-paid legal services
4) The Armed Citizens’ Legal Defense Network, Inc., a membership organization.
