I think that the possibility that you could be sued civilly is actually pretty reasonable guys and I think it would be wise for anyone carrying CCW legally to have a good relationship with a good lawyer or on retainer even, it just makes sense, most LEO's carry some form of secondary legal council to the Department be it union or other and there is good reasons for that. Even if you happen to kill the intruder/Mugger whatever you still have the BG's family that could sue you, Civil actions run the spectrum of valid to seriously flawed, its civil you wouldn't believe some of the civil actions that are out there.
I think the rest of the course sounds like garbage and while I am not soliciting here but I know of several LEO's that do provide CCW courses as well as supplemental training if you are interested PM me and I will forward their info.
