Sorted.

Issou and Vayran everytime they start making a meme:

Since you haven't provided any evidence supporting that you were the previous owner, or that you were supposed to get the property back if/when the gang closed, i'll assume there isn't any.

So since you don't have any evidence of that, then we can't do anything. We can't give you a property because you say it's yours. That's rather logical isn't it?

This is your own fault since you didn't create a contract with the gang leader.

Kain has created a forum section where such contracts can be created, so hopefully people wont find themselves in a similar situation again.

The Battle of Tamou's Sister, circa 2020 colourised

Members of the gang who are robbing the bank can kill any player inside the bank or immediately outside the bank.

Keyword: 'can'. It is allowing the people of the robbing gang to kill anyone without it considering death matching.

If you ain't the robbing gang the rule falls back to the basic server rules which disallows deathmatching without a proper cause.

As quoted from @Licano with an excellent reasoning:

Deathmatch is considered in the server the act of killing anyone without a PROPER reason behind it. Now, isn't a criminal that's helping the counterpart to get rid of you, your teammates and stopping the activities you're trying to do a proper reason?

Take away: The rule is bullshit.
