Laying down or standing up (if Prone) everytime I shoot to kill

Have you recently pressed lie down or crouch before firing? If so you are have internet lag issues which makes you revert back to the previous comman/commands. Also check your controls in the options menu, make sure all commands are as they should be in case you accidently changed a control. 

I don't think it was lag as it happens only when I kill someone or get really close.  I checked the controls and even cleared my cache.  I'm using an xbox btw.  I called EA and they have relayed it to the programmers to look into.  It could possibly be my controller but, as I said earlier, it only happens when I kill someone and random at that.  It's frustrating.

I would try another controler for troubleshooting purposes.
