Nobody, no government, no police force, no army, neither nor neighbor, nor your friends can guarantee your safety. Only you can guarantee your safety, and the only way to do that is to insist on your right to self defense, and your right to carry arms for that defense. Bans on weapons do not increase your safety any more than a ban on fire extinguishers makes you any safer against fires. It all comes down to you, and those in your immediate vicinity. In a perfect world there wouldn't be a need for self defense, therefore no need for weapons. But, we don't live in a perfect world. We, you, me, your family, neighbors, co-workers, associates, etc... are just naked apes. Some of those apes wish to take what you have, harm you or your loves ones, your neighbors, etc... The police can't be right there to protect you, they cannot be everywhere all the time, and in some countries the police are as much a problem as the criminals. There's a saying that the police are minutes away when seconds count, and it's true. Usually all the police can do is damage control after the fact. Take depositions, gather evidence, call the coroner to come cart the body away. Safety is inherent on freedom. You cannot have one without the other. The freedom to carry arms, the freedom to use those arms if your safety is at immediate risk, and the freedom from prosecution/persecution if you're use of those arms has been ruled to be right and proper.
Any person in any country that thinks to limit the citizens right to bear arms wishes to limit the freedom, and personal safety of the citizens around them. They place everyone around them at a higher risk to their safety, and they should be dealt with either as someone would deal with ignorant children by educating them, openly chastised for being an ignorant adult, or outright given pariah status and treated as if they do not exist.
