Someone insulted me and my mother and threatened to hit me. Can I call the police?

If you are going to war, you should have evidence to attack you, such as threatening text messages or recording. Otherwise, if you call the police, there will be no evidence, and the police will pass at most. If there is no evidence and you live near, you can ask the secretary of the neighborhood Committee for mediation. Anyway, you have to show your attitude first. You want harmony. You are law-abiding, positive and willing to harmonious social relations. Whether it's true or not, clean yourself up first, and then get the evidence. All the above must be well documented. You and your mother must reach an agreement, otherwise she may want to let nature take its course and hold you back.
