A good shop would probably be willing to show you how to string it if you buy the strings there.
Electing someone who believes that we should have laws and enforce them is exactly what we should do.
When she was a prosecutor, it was not her job to change the laws or decide which ones to enforce. If we don't want non-violent drug users and truants prosecuted, then we should change those laws. We have a process for that, and it doesn't include prosecutors making those decisions for us.
