How can the secret service let a 20y/o survalence a presidential candidates campaign site; see the guy with a view finder scope out the building your snipers are in; then let him grab his gun and climb in the building you are in?

Our law enforcement is about as useful as a pool noodle.

Spend some time looking into true crime. Crimes go unsolved not because the murders are geniuses. 9 out of 10 our law enforcement is incompetent.
