There should be no "required" training. There is no "required training" here in WA, never has been a problem. We can even carry into the state legislature and local government council chambers. Still never has been a problem. BTW: WI recognizes WA.
Anyone that is responsible enough to obtain a CPL is also responsible enough to know their limitations and how much training they need. The ones that don't care (or are not eligable) won't bother to get a CPL in the first place.
Look at a couple of the other threads here. Instruction offered on retention...people interested...but not required. Who (responsible people anyway) would not want a class on active retention?
