Police investigate collapse

If I wanted to upset people who were paid to look after my security; and planned to travel; which two countries would give them the biggest headaches?
Sometime's you have to ask these questions. I learnt that behavior was important in the CR, having read the 'Karlovy Vary' story; my empathy is with those entrusted with bigger things than book launches. I hope this all comes to an end that benefits the majority, and not an insignificant few hiding behind crumbling ramparts.
