I don't understand are those police officers or are they just security guards? Because where I come from, assaulting a police officer like this warrants the use of deadly force. Whats up with the Swiss? Don't the cops carry guns?
In most of the European Union nations, the police officers are not allowed to carry firearms with them. They are armed only with plastic batons. Even then, they need to be careful about using these batons. Else the suspect can claim that the officer used disproportional force.
