It is definitely possible that the opposite of this question occurs. It is possible that a majority of voters might support liberalization even though it would hurt a lot of voters if implemented. This is because people do not always have their best interest at heart. Sometimes, this is because of poor information (people might not realize that something benefits them/affects them) while some other times it is because other factors do not let people see the truth (such as intense ideological or religious feeling).
B people can choose to be religious
I believe it is the fire and police departments. My uncle is a firefighter and I think he told me this once
Hope this helps!
