Depending on the area I find most cops are in favor of citizens being armed. Now there are some who believe it should be concealed so they will harass people who OC or they do not know OC is legal so then they harass. Through people actually OCing many LEO have been educated on the legality of OC.
Saying someone open carries for the attention is like saying someone concealed carries for the opportunity to shoot a criminal. Neither statement is true.
