The second thought I had is people should have the freedom to chose their diet, some people don't want to eat meat from an animal that slowly bleeds to death, I'm vegetarian, I don't even eat meat. If they don't like the way his food is prepared, they can eat elsewhere. The police used a quick fix, they arrested the restaurant owner to calm them down. I don't know if the Sargent was sympathetic to the mob or they were under staffed and pressured to make a bad decision. The mob is wrong so they should be arrested for causing a public disturbance and damage to property, not the restaurant owner that is trying to defend his business and family.
There are even silly fools calling Harman Kapoor "Far right", a title used for Natzis that tried to exterminate minority groups. If he wants to serve meat that is non halal, that's his choice and he has a right to that choice. If you don't like his restaurant, eat elsewhere and leave him alone. And let the police do the hard decision and arrest the mob. The problem is the intolerant mob with too much time on their hands. Stop being layabouts and do some work.
