From what I saw in the two clips provided, you did not have valid reasons to have killed the individual who made the RDM tickets.
In the first one your friend runs in front of the guys vehicle, he stops and then you proceed to shoot him without any valid reason, it was clearly an accident.
In the second clip the individual gets hit by another car over into you and your friend (Nothing he could have helped), you get up give it around 15-20 seconds and decide to say "I'm gonna shoot the guy in the white car" even though it was clearly not his fault.
You were banned due to this being your 3rd RDM offence within the select time frame.
