You never admit shyt. That's not your job. Wait for your lawyer and stay quite, especially if it's serious. Your lawyer is paid to know the ins and outs and to fight for a better outcome for you. They might be able to get you off on technicalities if the cops are sloppy.If they literally got it on video, then isn't he actually helping them get leniency for cooperating? Lying when you're already dead to rights just increases your sentence yeah? But I'd wait for a lawyer to cooperate either way
