If I burn a house down, assuming it is vacant, and it is NOT vacant, I am STILL charged with a criminal offence..
Wreckless disregard for the potential damage one may cause is offensive.. them simply hoping they dont' hurt anyone does not lessen the offence at all...
If I fire a gun and someone gets hit, I get charged. Sure, some fancy lawyer could argue for a lesser charge than would be the case for a deliberate attempt to hurt someone, but you are suggesting because the damage is indirect it is sufficient to warrant it being kept SILENT.. I do NOT agree with that.
