It's close. Some disingenuously compare without factoring in demographics, but using common sense, it's easier for people to kill with firearms, and they are more likely to carry out a murder (less bloody, etc.). There's also a reason why those countries have law enforcement that have a better track on using deadly force against civilians, too ( e.g. less civilians with guns and less reasons to panic that an object is a gun).
How much do you estimate they number? It just seems like a distraction just to derail the merit of the protests. Law enforcement hasn't been without fault either, btw. Republican lawmakers also want to make it legal for people to run them over and give stiffer punishments for what supposedly is the "right" (i.e. they argue it's okay to take up arms against the government sometimes) thing to do in certain circumstances.
