Why is this so hard for people to understand? Her dad sells drugs. What would be your first thoughts if this happened to you in the same situation?
And the entire incident probably lasted less than ten seconds. Given that two cars obviously come out of nowhere and box her in, guys not wearing police uniforms jump out with guns drawn, could you even think for a second she panicked? She isn't a seasoned driver. Experienced drivers make driving errors under pressure. Her age isn'y why she was killed. Poor judgement by two cops is.
Again, no one has even attempted to explain how she was being used as a "decoy" as the cowardly DEA claim.
No one has ever been tipped off that a drug raid was about to happen, have they?
If the agents pull up and see a car with it's lights off pull away from the house they are about to search, what are they to think?
They will likely think that the suspect they are after is fleeing the scene.
They will then stop the vehicle allowing enough time for the suspect to leave through an alternate mean.
The driver of the first car, that pulled attention away from the real target, would likely be considered a "decoy" by most people.
