I think we'll soon see "this doesn't look right, <inserts location tagged photo>, figure out who to report this to and do the things" as a service.

I'm not even talking about lawsuits, but all the situations where you can report things to the government, but it's so much hassle that most people won't even bother. Things like labor / safety violations, violations of data protection and anti-spam laws, improper parking, that sort of thing. If reporting those could be as easy as complaining and posting a photo on Facebook or Instagram, a lot more people would do it.
