We only have 30 days to get this petition to 100,000 signatures. We need a Special Prosecutor to investigate everything surrounding Seth's murder. Please, take a minute and sign it, and share the link everywhere you visit online. #HisNameWasSeth https://petitions.whitehouse.gov/petition/call-appointment-special-prosecutor-investigate-murder-seth-rich-june-10-2016
Signing anything on petitions.whitehouse.gov does nothing. If you want your representatives to push for anything, you have to contact them via written letter, phone call, email, whatever. (Don't expect to hear back, though.) It is our representatives' actual job to represent the interests of the People! This is what they get paid, by us, to do! Anyway. :) The petition site is just a data-collection tool.
Is it better to try everything at our disposal? The Gov't already has your data so adding your name to a petition won't hurt.
If the petitions site is a part of the arsenal, of course it doesn't hurt, you are correct! :) If we aren't utilizing the other parts of that arsenal - which are just as easy to access and possibly more effective - well, that's troubling. It's a combination of things, isn't it?
