Also yes it will, it will make it much harder for people attempting to buy weapons and it will overall put more pressure on people who want to buy guns as they know it will be illegal. It also means people can't just walk around the street with a gun with them and have nothing happen to them.

Alternate weapons, that means less weapons, less lethal weapons too. This is still helpful. Knife attacks are much harder too pull off than a gun attack, explosives are much more complicated, and vehicle attacks take out less people at a time and is overall easier too stop. This is overall still helping stop/reduce overall attacks and making them less lethal in some cases.
