i recently was suspended from school for possesion of marijuana. i came into my school with a friend after a quick smoke session and we smelled like pot. they brought us into the office and asked us where we had been, we were asked seperately and unfortunately we had conflicting stories. we were then searched and in my locker they found about a gram of weed and a lighter. WAS this an invasion of my privacy, or is it standard legal procedure? i appreciate any imput, thanks
