Descoring cones

Hey can anyone tell me if we can descore opponents cones if thry arent in the safe zone.

Please refer to the game manual:

Long story short, no. You can descore from your own goal but any kind of descoring of opponents goals is considered sabotage and you may be disqualified. My team toyed with the idea for quite some time but everything in the rule book makes it to risky and pricey to attempt. The best bet is hoping your opponent knocks down their own tower.
