Some people argue only foreigners commit crimes and therefore walls and fences should be erected to keep out every single foreigner. That tactic won't work. See, we all are foreigners to people from other countries so basically we should shut out ourselves. Which is quit impossible. Hungary may try. But I predict putting up more and higher border walls will not make the people from Hungary feel more secure. http://www.zerohedge.com/news/2017-05-14/hungary-unveils-new-electrified-border-wall-watch-towers-and-guards-machine-guns
Think about it: they don't want the Sharia in Hungary, meaning they really hate the idea of every citizen being watched and tracked and angry heavily armed men on every streetcorner. And how do they come about preventing that scary scenario from becoming reality? By putting up security camera's, tapping phonelines, checking random emails and...putting angry heavily armed men on every streetcorner.
Feel safer already?
'Daddy, why is there a fence surrounding our town?'
-'To protect us from people who want to lock us up, son!'
'You can't be free behind a wall'
