I won’t speculate on how much energy they are able to put into other efforts because I don’t have any actual experience with the judicial system. A few days behind bars are not enough to stop one from participating though.
The public messaging is that people painted Stonehenge. I’d say the clarity of their messaging is exactly the topic currently up for debate.
Now imagine this was a group that also engages in constructive participation. Suddenly the messaging of that group would be very messy, full of misunderstandings. Instead of this they do activism that will not be favourable in the public opinion under that specific organisation where it won’t hurt the constructive efforts.
