Most advantage for a LE is that there is no waiting period to pick up a handgun, they can purchase and walk out the store as soon as the proper paperwork is finished.
Not in Washington State. Here, the only way to avoid the state waiting period on handguns is to have a Concealed Pistol License. Well, most cops here don't have CPLs; they don't need one to carry concealed, so most don't bother to get one. But that means when they buy a handgun they have to go through the waiting period. Stupid, huh?
