They are already too powerful.
Much of the illegal actions they take are done through coersion and intimidation. They aren’t satisfied with airports; they have branched out to other public venues, highways, and they will be on your neighborhood street one day. They have weapons that a strike unit in the military would drool over. They have armored MRAPS and other strike/command vehicles.
Obama’s 2008 Civilian Defense Corps, as well armed, as well funded as the military. A Gestapo meant to oppress civilians, period.
they are also on the water - in Florida they have taken over FWC, Florida Fish and Wildlife Conservation Commission - (what used to the game warden functions)- they now give out water traffic tickets - I hate them, they are aggressive, run the waters in unmarked boats and they openly violate our boater registration laws - i.e. their boats have no registration sticker or “FL-Numbers”
