Best defence is ignoring, so simple is that. Defend yourself from terrorists, do not care!
If you want to care, then I suggest you watching some execution videos from old Nazi or Russian times. Or even modern hostage execution videos from so called terrorists. Or russian mafia videos.
Many people have no idea what is going on in outside the borders of the state/news area. So now wonder why they are crying. If you knew most of the things, you would probably kill yourself.
