IS THIS FISHY...

What's the evidence or theories put forward by the people claiming it was an assassination?

Here's an example in one of the articles I found -

Skeptics of the official narrative have highlighted eyewitness accounts which state that Hastings’ Mercedes “exploded”.

Images of the vehicle appear to show more damage to the rear, around the area of the fuel tank, than the front, leading to speculation that a car bomb which ignited the fuel could have been responsible for the incident.

“No matter how you slice this particular pie, a Mercedes is not just going to explode into flames without a little assistance,” writes freelance journalist Jim Stone. “Car fires in new cars happen for three main reasons — running the engine out of oil, or running the engine out of coolant, or after an absolutely huge car mangling accident, having the hot side of the battery short out against the frame before it reaches the fuse panel. And for all 3 of those normal reasons, which account for virtually all car fires in modern cars, the fire would have started in the engine compartment, progressed slowly, and scorched the hell out of the paint before ever reaching the gas tank. That clean paint is the be all tell all, Michael Hastings was murdered, and the rest is detail.”
