Not in every country. Singapore is fine. The only riot in 40 years was over within a couple of hours as the police that was immediately sent on site outnumbered the rioters by an order of magnitude. You occasionally see panels on the road warning you that a pickpocket was active there 4 years ago, or maybe it was a car crash, and could you please phone the number if you have any information about it.
The country has at least four major religions and four official languages with considerably larger minorities than any European country, yet, has not seen a race-based breakdown in the rule of law in decades.
It's a failure of government when the rule of law breaks down. It's up to the citizen to figure out the problems and solve them with their votes and by talking to their elected politicians. What have you personally done politically to change the situation in your own country? Personally, I've given up and emigrated to a country with better individual rights.
I'm not sure closing all borders and living in autarky (which is where the UK and US seem to be heading) is a good long term choice. Not my countries, not my problem. It saddens me a little nevertheless to see so many great countries pick it.
