One problem with your scenario.
Explosive residue would be present on the pieces of the car.
Investigators “in on it” would take care of that problem, of course. But if you accept that scenario, then you can’t take the results of any investigation as truth.
Unless of course it matches the conclusion you have yourself jumped to.
“Explosive residue would be present on the pieces of the car.”
Of course there would be, Sherman. The car smashed and exploded into a fireball at 100 mph.
Nice try, but the fire would destroy your mythical residues. But we understand why you jumped in with your effort on the oligarchs’ behalf. The more you do that the more obvious it becomes about for whom you work FR.
