Simple concept, add a /tackle command where, if a player is punched, you can tackle that player.
I know people will say this is easily abused. I would like to also suggest very strict rules relating to the tackle script - you should only be able to use it when chasing someone or if you're catching someone off guard.
This is very useful especially in law enforcement roleplay. The usage of tasers is frowned upon nowadays on RP servers.
This could be helpful command/feature especially for the cops, If they are chasing someone on foot they could tackle you o/taze not bad idea at all. Adding a timer between each tackle to prevent abuse is something I highly recommend like you have to wait 5 or 10 seconds to use tackle command second time.
