The end result of this crash is brought about by simple physics. A Ford Crown Victoria (CV) when loaded with police gear weighs about 4,900#, more in some cases, (trust me I've weighed one). A Chevy Beretta has a manufacturer's curb weight of 2,756#.
When the Beretta was made there was no NHTSA side impact crash testing or safety standard. Additionally in 1994-1995 some Berettas were made without a reinforcement panel in one of the rocker assemblies, reducing side impact protection. The Chevy was built to a safety standard over 10-years old and was struck in the weakest structural point. In this area there is no crumple zone and the striking vehicle is mere inches from occupants.
Look at the math: the CV is 4,900#, decelerates from 25 MPH (36.67 FPS) in a distance of approximately 8-feet (the width of the Beretta plus a little more). The formula for the amount of G-force in such a crash is: G=(S)^2/(30)(D). The impact generates 2.6G's, multiply weight by G and the CV exerts 12,760# on the Beretta. Up speed to 30 MPH and force rises to 18,375#.
A 2,756# car struck in its weakest point with forces up to 6-times its weight or more, is NOT going to fare well. The Beretta is going to suffer a significant amount of damage, consistent with what you see here. The lack of skid marks can be accounted for by one of two things: either the CV did not brake, or the ABS prevented skid marks.
It is time to face facts, Mr. Gray was driving a car that was at least 10-years old, weighed 2,000 pounds less, and was struck in an area that was the weakest part of the vehicle. Either way, this is a tragedy, but it would have the same ending if the striking vehicle were a civilian's SUV, pickup truck, or other large car.
As far a PG Co officers not obeying the speed limit, about the only time I've ever seen a police cruiser going the speed limit here is if it says "State Trooper" on the back. PG cops do indeed drive as if they are above the law, routinely going well above the posted speed limit, only to in turn cite motorists for going 3-5MPH over it. Not to hijack the topic at hand, but just today I was coming back from the Vet's office (animal) on Route 4 and I saw an unmarked cruiser swerve in and out of traffic without his lights and sirens, only to be left as the 5-6th car back from a stop light. Rather than wait, he turns his lights on and expects the left-turning traffic (with right-of way via the stop light). No one stopped for him because they all saw and knew what he was doing. After he passed the light he turned his lights off and had to be going at least 90MPH because by the time the traffic at the light started moving, he was a dot in the distance.
My deepest sympathies go out to Ms. Gray. Brian's place of employment (TJ Elliott's in Bowie) is a regular meeting place for many local politicians - hopefully they will get involved & help Ms. Gray.
No way that damage was caused by car going 25MPH.
