The types of crime that would happen in an airplane would already be identifiable due to its constrained cabin, so I don’t understand the comparison.
Let’s use your example for say a concert. Is checking bags worth it? Would crime go up if there was no bag check? Why or why not?
My point was if you are only looking at the reduction in crime as the sole success criterion we will all end up naked in glass cells because that would result in the lowest crime rates.
> Is checking bags worth it?
Probably not. It's mostly there to preserve the profits from alcohol sales.
> Would crime go up if there was no bag check?
Did it go down when they added them?
