Magna carta assured you the right to lawful protest (ie refusal to pay taxes)
It also introduced "every man's house is his castle" and castle law for the common people
It gave you the right to defend yourself if under attack (now we are supposed to run away from the attacker)
It never mentioned things like the consumption of alcohol or other known drugs at the time, because a man was a free man
It gave men the right to live off the land that was considered public land (try setting up in a forest and they'll boot you out faster than parliament can push through kneejerk bills)
It forbade the rule of royalty by divine right (like the queen rules today)
Well, Im not too fussed atm. Imo the most significant aspect of this saga is that the police say that the law is mostly unenforceable because they would need to hire an RC expert for every case they had just to identify the substance. Is there anyone that can do that, just thinking of the dozens of cannabinoids released for example etc? They will probably just confiscate everything and have done with it, for any one unfortunate enough to get caught with any pre-ban stuffs.
So once again the law and war on drugs become a total mockery and a dismal failure. Those 'in power' are seen as ever more out of touch with basic realities. They haven't even got the basic approach right.

You should be too fussed because no matter how much egg parlaiment gets on their face
they get away with it over and over and over again this is because English citizens (I'm in NI but I would stand up for my rights if I lived in England) hold a 'stiff upper lip' for every right they are stripped of. Free speech online? Gone. (Unless you complain about straight white males) common law being turned on it's head? Happening soon. Porn bans? Yep and not just kiddie porn either (though I'm sure many a minister has a stash of that) if I lived in England I would attempt to lead a march on parliament, however I would be arrested just for sewing the seeds of dissent (a man here is doing a jail term for trying to get the public to march on Stormont (our joke version of parliament)) so you cannot even stand up to the
public servants who you elected for making a mockery of common law.
Change needs to be made and no change can be made from a computer screen. Taking nitrous outside parliament was a huge mistake; it just rectified in their small, small minds that 'the druggies and junkies' are a bunch of fools. What they should have done is set up a real protest outside parliament.
The UK is going down a very dark path indeed, just like France did before the revolution. I wonder if I'll live to see the use of the guillotine on British soil.
