It would be cool for DHS to have metal detectors they could plop down at events. That way they can have an easy way of knowing if someone has a gun or not. It may not be 100% effective compared to searching someone (like it detects all guns but not knifes & crowbars).
This would allow for people to still smuggle stuff into events but not like high powered weapons like guns.
I think it would be cool. Thoughts?
