You Can Create A Law But Police Have To Be Behind Enforcing It

I'm not sure many police persons are going to arrest people for giving others water in a voting line. THere are a lot of laws like it's illegal to spit on the sidewalk that are totally ignored. I don't see people enforcing not letting people give water. If enough people ignore a law it becomes almost impossible to enforce. Laws are made to create justice what forms of justice is it not giving a person water.
