The Mandalorian discussion thread

I know I'm late, but can someone explain the justification these two gave for why these 2 Mandalorians can help them and not the other Mandalorians that were already there? I've watched the episode twice now but I still don't get it. You're in charge, but you have democratically elected laws in place. Okay, got it. Arms aren't allowed into the city, but you let Bo-Katan and Din Djarin into the city. Mandalorians can't come in, but they can? Why? Their explanation just seemed like word soup more than an explanation.
The explanation given kinda makes sense....Bo and Din are Mandalorian, their weapons are part of their culture, so they are allowed to keep them on them, kind of like Jedi are allowed to keep their lightsabers on them in similar circumstances. The other Mandalorians aren't allowed in the city because they are armed militia under the pay of the city, city ordinance doesn't allow for the city to have armed security inside the city limits, therefore, they have to stay outside of the city. Allowing Bo and Din to act as "investigators" without actually paying them to work for the city was like a loophole in the law.
