It's not in your head, it's real - I constantly read about kidnappings, carjackings, extortion, etc on Tsikot and that does not represent the entire situation well but just what people can report online. That's just the tip of the iceberg, so to speak.
You're right, punta ka na nga lang sa mall you'll feel paranoid pa. Maglalakad ka lang sandali sa city streets, you'll have to be vigilant. This is the other side of your question I guess, the individual safety of citizens. I guess it's been like that for a while and people have adapted ways to cope with it. However, that's the problem - it's been like that for so long and nothing is done to make it any safer.
