As much as the TSA likes to tout the guns they find this quote was what got my attention.
Agents also caught 13,379 people with knives less than 3 inches long and 2,994 with longer knives.
Almost all of the knives are someones pocket knife, most likely they forgot to take it off their key chain or out of their purse. When they provide the statistics on "Red Team" tests then we'll know how effective they actually are.
