You have pointed out the problem with "May Issue". In theory the "May Issue" thought is great but sets it up to be ripe with cronyism and graft depending on the whim of the sheriff or judge with the power. To overcome this states must got to "Shall Issue" and make the sheriff state why they are denied rather than "I don't like him or he didn't contribute to my election". Local issuing of permits sounds great but leads to discrimination.
Good luck to all those affected.
