Dallas police officer ‘executed,’ 2 others injured in targeted shooting
So what you have here is a planned execution and subsequent ambush on the Law Enforcement QRF (Quick Reaction Force or back-up).
These types of guerilla warfare tactics were used by insurgents in Northern Ireland and Iraq and Afghanistan time and time again with great success.
As the next phase of The Great Replacement/Reset kicks into gear (Anarcho-Tyranny) expect to see much more of this.
Prepare Accordingly.
