Police say they have plan for air support after sale of helicopter

Actually, the Guard can respond as law enforcement under the Guard, Posse Comitatus only kicks in when they are federalized. But that doesn't mean that they are going to be able to respond quickly.

posse comitatus means "power of the county",whereas a sheriff or deputy may command any male over the age of 18,to assist him in performing his duties,or be held criminally liable.JCSO.

Guard soldiers can make arrests if their commander allows them too. They have the same authority as state police and can take over a scene from local or state police if they want to. In other words, armored vehicles, gunships and M-16's will always trump old Crown Vic's and Glocks.
