I don't recall anything like the killings of those police officers happening at a demonstration, we're talking organized targeted response here.
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
I'm not aware of anyone since the Black Panthers trying armed politically organised retaliation against police violence. But I could be very wrong.
Edit: well, this turned out to be wrong.
One of them is apparently dead so I figure this will be known quite soon.
And I really wonder why you'd make that assumption on a 50/50 basis with 0 evidence, is there something specific that makes you write that?
US police have shot and killed over 500 people this year.
So far 58 officers died "in the line of duty". 26 of those died by gunfire.
In 2015 130 officers died in line of duty, 39 of those died by gunfire. (I don't know how many of these were killed by other officers).
