That is the paradox of authoritarianism. No matter how comprehensive, it is always possible for an aggressor to fly under the radar and work the system against you. Hell, you don't even have to strike back, you can be singled out for punishment by the authorities simply for being attacked, which marks you out as 'being involved in trouble making'. The actual aggressor will have melted from the scene at this stage, leaving you in the spotlight.
