There are a lot of good reasons why you don't hear about sabotage to industrial sites, arms factories etc. It's all undertaken by very small, clandestine affinity groups who rigorously vet their membership and don't communicate online (they'll sometimes use repeating mesh networks to communicate or through numerous proxies/via TOR etc. but never on their phones). The people doing these actions are probably some of the same people involved with your local Food Not Bombs collective or infoshop, but you're never going to learn which ones are doing what because no one talks. No one is going to tell you about planned actions unless you're in the group, and you're not in the group. Back when I was the most involved with local anarchists I only had the vaguest notion of who might be involved in any undertaken or planned clandestine action. I could guess at best, and there's a solid chance I'd be wrong. People involved in what was going down knew that I wasn't physically up for that kind of stuff, and although they trusted me enough to man a table at a book fair or watch over the space or help out with all sorts of other stuff, they kept to their opsec and so they never told me. Good on 'em. Anarchist groups are really not looking to draw any more attention, which is why the most that you get is an after action report on some counter-info site posted anonymously by an intermediary, and which keeps details vague. I knew of actions that resulted in dozens and dozens of cop cars being sabotaged and put out of commission for weeks. I was probably acquainted with people who did it, but I'll never know. That action never made the local news.
Anyway, there are ways to do these sorts of things is all I'm saying.
