This should be like a captcha but with a bomb that you can either throw at a bunch of people or an empty area and if you throw it at the people you need to redo the captcha

So terrorists would be stuck on this screen because they kill people so it's impossible that they'll do the captcha right! I'm a genius! :D

I wonder what happens if you press yes. It would be kinda boring if they just like extra searched you or something
