Depends how you interpret violence. Blocking the freeway is essentially holding people hostage for as long as you’re blocking it.
I think 5 years is extremely harsh but I do think a shorter prison sentence is a fair punishment.
You could be putting people’s lives in danger by doing it and even if you aren’t, you have no right to stop other people from going where they’re going.
If someone stopped me on the streets and refused to let me walk down a public street, that to me would be trying to hold me hostage and I’d react accordingly.
What does attention in this case help other than more people saying “look at those idiots blocking the road”…in my opinion it may even detract from the cause…
On the other hand, if the CEOs of the companies who are polluting our world and the politicians they’re successfully lobbying have to live in fear in their own homes, shit starts to change quick.
