Actually the Constitution does address the death penalty. It requires it as punishment for treason, so it certainly is allowed for the states to impose it, if they choose to do so.
Yes, you are correct about the punishment for treason.
Does it allow for the punishment of murder?
I contend that it is the states right to determine that.
I contend that it is the states right to determine law concerning abortion as well.
Honestly, I am pro-life. I feel that if such a thing were actually put to a vote, it would end. I think it would turn the voting public’s stomach to decide that. I think part of the issue is that it is now convienent, the public doesn’t ever have to think about, unless they want to.
Now, if they HAD to think about it, by way of the ballot box......Hmmm..... I wonder.........
