What @McDili and all staff are saying is this:
- If you shoot at some scrub in Kavala with a rook without engagement and miss, they return fire, then you kill them, that is RDM for skirting rules
- If you shoot at someone tires WHILE THEY ARE IN VEHICLE without engagement, and they get out and shoot at you, and you kill them, that is RDM for skirting rules
The reason is this, you initiated shooting at them without RP. The fact that its a car or tires is irrelevant, its the fact you fired 'reasonable' at them and then killed them without engagement. There is NO BAN for 'Attempted RDM' - however the player you attempted to RDM is allowed to defend themselves...if you continue to shoot at them, your initial engagement was against the rules, therefor until the engagement is over (5 mins of no exchange of fire or chase) you are NOT allowed to kill them since your part in the engagement was initiated by breaking rules...

Think of it this way (this analogy is for @Dante )
In hockey - if i cross the blue line (engagement) before the puck, I am offsides (or breaking the rules), but I am ok, as long as i or my teammates don't touch the puck until i cross back over the blue line (engagement over). Then I am allowed to cross the blue line again and attack the puck (engage) within the rules.
