if this guy walked into a theater loaded with knives only...

108. So I can still carry a box cutter

and a ceramic knife onto a plane, no hassle, no fuss, no bother? You be sure to try that the next time you go to board a flight, and see what happens.

If you're going to use 9-11 as an analogy, you might want to think it through to see if the analogy works in your favor. In this case it clearly doesn't, since, if memory serves me well, the response was to ban box-cutters and ceramic knives (and lots of other things) from airliners.

So, following your analogy, are you proposing a ban on firearms in all theatres?

BTW: it was't just the box-cutters and knives that were used to commit all that carnage. I would argue that several airliners moving at hundreds of miles per hour, along with tens of thousands of gallons of aviation fuel, also had their part to play in the atrocity.
