Should public school days be extended one hour?

          I think public school days shouldn't extended one hour. First, what if student have to pick their brothers and sisters from their school or let them in the house. Second, violence could happen. Third what students wanna go out
 
     My first reason is what if students have to let their brothers and sister in the house or pick them up from school  if they don't pick them up from school they can get lock out of the house and they would be sitting out front for another hour because the parents could be at work till late and they depend on there older kids to pick up there little brothers and sister.


My second reason is violence the public school is worried about their students geting into trouble when they are not in school long enough but if we get out late and its so dark who going to know that your hurt or not you can get jump waiting on the bus stop and they wont know who did it if they get out one hour after school.
