> he has reasonable cause to believe is committing or is about to commit an offence

Punish the person who starts a fight over some tacky device name that is trivial to ignore. That is the person that is committing (or about to commit) an offense.

You're being unreasonable. Think about what you're saying. It's the equivalent of "You can't wear that shirt, someone might get offended and punch you in the face." We don't act like this in society. You arrest the person who throws the punch, not the person wearing the shirt. Just the same way you don't arrest a woman for wearing something slutty, you arrest the person who sexually assaulted them. This is the definition of victim blaming. It doesn't matter if the victim is increasing their odds of being victim (unless they are actively seeking out and attempting to become a victim).

Be reasonable. Punish the person who is actually committing the offense. Don't punish someone because of some imaginary offense.
