Ha, ha! Now look what happens if you refuse the nice young lady. And then the other one... Shame on you.

Seriously though, that photographer and his friend are childishly stupid. I understand when child refuses to take medicine even though he's sick, after all that injection hurts some. But these folks look like adult members of similarly sick society, and what they were nicely asked for was not even nearly as painful.
Refusing to collaborate with police in their anti terrorist actions is plain stupid. Now they complain how rude is the police asking for "more detail". But what would they say being injured by terrorist act? Or even worse - losing some friend or relatives? Now they would complain how helpless the police is in being not able to stop the terrorism...
It's the one way or another - either we help and collaborate as much as we can to prevent this problem, or forget about it and protect our privacy more than our life. It's a simple choice. Just like with a sick child - injection or death...
