This is one of those "not to do things" that should be fairly obvious to everyone. A Boston man was arrested wearing body armor and carrying a load of weapons ... in an airport.According to CBS Boston, Yongda Huang Harris, 28, was taking a trip from Japan to Boston when the good ol' customs agents at LAX in Los Angeles stopped him at the airport.

I mean, really, what was this dude thinking?

They found a load of goodies (not candy) on his possession, including smoke grenades, a collapsible baton, billy clubs, a face respirator, knives, a hatchet, body bags, a bio-hazard suit, handcuffs, leg irons and a device to repel dogs.

And did I mention his bulletproof vest and flame-retardant pants?

He is now facing a bunch of charges and maybe five years in the gray bar hotel.
