How did he even get on the base? Whenever I visited my son, I had to fill out a form. My purse was searched, and my car was checked out. Have they relaxed at the gates in the last couple of years?
It's actually really easy..observe...
Civilian gate guard: ID please.
Bomber disguised as soldier: (pats pockets) oh crap...I left it in my computer when I went to lunch...I'm sorry man!
Civilian gate guard: let me see your drivers license
Bomber disguised as soldier: Sure thing here you go!
Civilian gate guard: (looks at DL front and back for about 2 seconds) Have a nice day.
And just like that he's on post and free to his bidding.
