I am not saying leave them out in the road. Remove them and arrest them. But 3 years in prison? No.
Obviously you have never witnessed as to how these glue-bastards operate. After separation from the road and taking them away - either the same person runs back or another comes in, to take his place. As such it usually takes 3-4h to clear a road of them.
It isn't really the police's job to separate them from their glue and the road - that is mostly done by paramedics. As such they also drain away paramedic resources from doing their actual job.
The issue to me is that these glue-bastards are:
a) participating in a non-permitted protest-action. - needs to be punished (usually by a fine)
b) intentionally hindering other peoples movement - needs to be punished (usually by a fine and/or prison term)
c) intentionally causing economic damage to a country - needs to be punished (usually by a fine and/or prison term)
d) intentionally causing "disturbance of the peace" - needs to be punished (usually by a fine and/or prison term)
e) intentionally endangering other's peoples safety - needs to be punished (usually by a fine and/or prison term)
f) resisting arrest or refuse to follow instructions by the police - needs to be punished (usually by a fine and/or prison term)
g) intentional action not committed simply by an individual - but an organized group action (usually by a fine and/or prison term)
If you take only a,b,c, & d - the total filed charges, already amounts easily to a 1 year prison term. Fines are useless in regards to putting an end towards such actions - since their organization isn't poor at all. And most of these glue-bastards are able to proof - no income, which in return is normally handled by courts via sentencing the offender to prison time.
A,b,c & d, also is enough to define a person to be not just a protestor - but a
political activist, pursuing a particular personal political agenda, that is not necessarily supported by a majority amongst the general population.
Therefore if e.g. political activists would use the same methods to e.g. protest against LGBTq rights - (wanting to protect human mankind and their families from pedophiles and moral decay) - they would in majority of all cases be punished far more severely. Why?
Because the factual problem in e.g. Germany isn't the absence of laws - but that Judges are (depending on the state) to a large %, up to a majority Lefty&Libs - whilst the general population is not.
As I had stated already many times - Lefty&Libs had 40 years time to get prepared - via constant
activism, and not e.g. MAGA's who sit at home and write - pestering the internet with nonsense and tough talk - whilst believing that voting for a useless human scumbag or any other sort every 4 years - would change matters.
