A felony is something that really is on your record forever.
Some presidents have admitted to using drugs in their youth, some may have also sold. Yet presidents usually push for stronger drug laws. The point is, if they had been caught, then they couldn't be president at all.
We were all young once, & a lot have done things that they know if they had been caught, it would have changed everything.
Push to grant more amnesty to the youth that really deserve it and prove they have changed their ways. A "sealed" or "expunged" record just hides the fact that they did something in their past. It still may prevent them from serving in the military or other government jobs.
