No for both. Criminals even if not convicted are not trustworthy.
interesting view - so if the arrest record was actually longer than this you 100% wouldn't trust the offender?
Doesn't matter if he has committed one crime or multiple crimes. He is not trustworthy. However, in one of your cases, the one who owns a license to a weapon is not considered a criminal and hence can be trusted. I can't say in the case of manufacturers or ones who sell it as most of them cannot be trusted.
