Even if you had a gabillion dollars, you could hire a lawyer, but those convictions will never be removed or even sealed.
Sure, there are laws that PERMIT you to go through the motions of sealing the convictions, but they aren't really sealed.
Even if NH seals them, there is the matter of the FBI and its national crime repository.
The mugshots that were taken, the fingerprints you provided, even your DNA are all safely stored by the friendly folks of the FBI and their DOJ masters.
No, mate, save yourself the worry, fuss, anxiety and the loot.
Forget about pretending to have your records sealed in NH, when right across the border in VT (even in NH) nothing has changed.
Unlike in the 17th or 18th century when you went to prison as Roger Roach, got released and lived your life as Chester Cricket.
Society, rather our puppeteers, betters, masters make you pay that debt until the day ou die.
Unlike our ancestors, the debt is never paid even if you did 50 years in prison, the puppeteers demand more!!!
