Should #Prisoners Be Allowed To Vote?

If the rule is: If you know right from wrong, you go to jail. If you don’t,  you go to a mental institution.

If that be true: Prisoners have chosen to do wrong

Why is the government giving some prisoners the vote, in the UK this option was reviewed. 

Having initially said prisoners serving up to four years would get the vote, ministers now plan to give the vote to only those prisoners sentenced to serve a year or less. However, they are aware this policy will be tested in the courts and they might lose again.

Why only up to 4 years? Let’s suppose this was the USA, I don’t know but are the Electoral votes comprised of all residents? 

Prisoners are counted at the location of the prison. However, I would suspect they are released to their hometown.

What are your thoughts.
