I take it you haven't practised Iggle ! Who is anyone going to be looking for? Who in the world is the only person who gains from a gang turning up and evicting squatters (by force or otherwise) from your property?
Or do you expect the court to believe that there are gangs of bouncers roaming the country evicting squatters , to no benefit to themselves, motivated by pure high-mindedness and nobility and selfless help of the owners ? If any of the perpetrators, 'bouncers', whatever, are caught prosecution counsel will have an entertaining time asking them why, exactly , they did it, and hearing what they say.And all, in fact, all the time knowingly risking certain jail sentences if they're caught ? For what? What, for a man who never asked or suggested anything, never said or anything at all which might cause them to do such a thing and, who gave them nothing?,Would you believe that?
Chances are they'd grass you up anyway, in interview and in court.Why should they go down without taking you with them?
The circumstances are enough evidence for a charge and conviction.Using force or unlawful threats in such instances are regarded as very serious.The courts don't like 'taking the law into your own hands' very much, at the best of times
