An absolute +1 for this, the other day myself and another SC0 officer were arresting someone and they were shouting at us saying they have a gun licence but had no way to prove it even though they were running around with a smg/rifle out. If there is a way to add a licence that stand out clearly it would be great, and maybe add some licence tiers such as a Class A licence for rifles and shotguns, Class B for SMG's and Class C for simple pistols. Knifes i think should be kept illegal and enforce a rule that states you cannot have a knife out and say "oh its under 3 inches so its legal you cannot arrest me" as theres not even a rule on it so people argue its an unfair arrest then make psd / have a DO sort you out.
