Several years ago, I remember a case in I believe Kansas City were some dumbass was open carrying a Glock 17 topped off in a cheap Fobus rig in Subway. BG walks in, sees the Glock, rips it off and bolts. Dumbass chases BG out the door, gets shot twice, dies and BG runs off. Now you're dead and BG has a purdy Glock with 16 rounds.
When I turned my badge in was the last time I ever carried a weapon in open view. The only people that need to know I have a gun are me and the BG when it's time.
Only time I openly carried was when I moved to Crossett Ark. in fall of '71. Found out you could there so I strapped on my Browning 22 pistol (well actually it was my brother's) and went to WalMart and walked around nervous as all get out. Once and only time.
