I WANT MY MOTHERFUCKING KNIFE BACK!!!!!!!

ok guys so i recently took the greyhound bus back home from New jersey where i was visiting my family, And the whole ride from Jersey to the end of georgia i road the bus uninterrupted and as comfortable as possible. It wasn't until we got to Jacksonville where they made us all get off the bus and then searched us before getting back on that i had been searched while taking the greyhound bus. Amongst other things they confiscated my pocket Knife, claiming that they were taking it for safety reasons and they said that they could mail it to me for $10. When in fact that is the reason i had a Knife in the first place. Do you all think that they should be able to take something like that when people carry those thing for security? And what about the people when you take there security away? You don't know where they live or whats going on in their lives, so why should you leave them vulnerable like that? Any thoughts?
