@ Foxy thte issue is now is that those in power are trying to proof that they are the law.

Dear Rollyczar,

We don't need to know - why should we?

So we become scared?
So we convert to Islam in an attempt to save ourselves and our families?

Unless there is something concrete that we should do to avert an imminent danger, such as to hide under the table or to take axes with us whenever we go to a concert or similar public events, we better never know about such distressing, yet sporadic, events. It's not only unhelpful - it's damaging.

If you personally cannot prevent it, then leave the work of prevention to the security forces.
