Note that "snipers" doesn't mean people with a sniper rifle like in the movies. Apparently one of the shooters walked around with an assault rifle, but nobody said/did/could do anything because Texas is an open carry state.
This man was accused as a suspect on twitter, but he turned his weapon into police and went into them lying to him saying they had evidence and witnesses. While, on social media, we had clear video of him walking the protest and hitting the deck when shots broke out.

Police initially suspected someone who was walking around with a rifle, but he turned himself in and was later released.

Was one of the killers walking around with a rifle?
A lot of the argument for the 2nd amendment is that if you put people open carrying, the gov/police will show more restraint, allowing for 1st amendment practice. https://www.youtube.com/watch?v=mSwys0dm_EA
In this case, was it a large weapon? Did the "snipers" carry around their guns openly?
And I'm not sure what the physical size of a weapon has to do with anything.
