Downtown Dallas: Police officers shot by two or more snipers from elevated positions.

[Peter Lemkin]

Don't you need three shooters to triangulate? (triangle = tri = three)

No the "triangle" is two shooters and one target.

I'd call that crossfire, but there is NO standard definition/distinction between triangulated fire and crossfire...
That said, they originally said [the 'officials' of Dallas] that one shooter had been killed while others were firing from multiple positions. Now, it could have been an 'honest' mistake due to the confusion, but it needs to be explained how it went from them being sure of multiple shooters at high locations in tall buildings to one guy on the second story of a building. And why did they feel the 'need' to blow him up when he was then not a threat to the remaining officers and public? Increasingly, police just don't take people into custody anymore, they simply execute them...and not to save taxpayer money. It is all part and parcel of the militarization of the Police in the USA, who see any suspect or perpetrator as the 'enemy' to be 'neutralized'. Less and less are lawyers and courts needed...as those who might have otherwise have gone into the criminal justice system [sic] are instead buried. A few years back there was a man on the loose talking about wanting to kill police [I believe in N. CA] and though they had him surrounded and not a threat, they burned down the building he was in. One can site so many examples of this - and nothing happens to the police, not even a question of their tactics. The bizarre rule of engagement that it is OK for a policeman/woman to use lethal force if they feel their lives are in danger is ludicrous. Their job entails regular endangerment or ideation of endangerment - and they shouldn't just be allowed to kill anyone on that real or invented 'say so'. This specific event was not the idea of any individual officer, but apparently a well thought out plan by the heads at DPD to send in the robot with the bomb. It is the same mentality as drone strikes or that used at the Mai Lei massacre, for example. I find it a very troubling trend in police state Amerika.
