The point here is that he shouldn't have been detained in the first place. Did they think he posed a hazard to flight safety or not? I very much doubt they felt he posed a risk and were more than likely just curious about what was in the box maybe perhaps even planned on stealing it. Law enforcement was given too many freedoms under Bush and much of what was done needs to be redacted.
Where is the line to draw in this so called protection? I will not and many others trade in our freedoms for protection they can't provide 100%.
Gun laws does the waiting period as well as restrictions really help? Tell me if someone is going to murder someone or others do they need the gun or even so what's to stop them from getting one in the first place if they really wanted to? Airlines and all the restrictions on carry on items. How is this going to stop someone that has planned this that really wants to from getting a knife or a gun on the plane? We are giving up rights and choices for a sliver of protection that only goes so far and in most cases against poorly planned attacks.
I'm sorry but racial profiling with decent training will usually cover our asses enough instead of shedding all our rights to the "man".
The further we go down this road the more likely we will repeat our civil war or increased rioting or civil unrest. Breaking points become that much more realistic.
