The other side of the relocation is that you have put a raccoon or any animal for that matter in the territory of another.
There will be fights and typically the rights holder to that territory wins thus sending the loser off or killing it.
You may have dumped your problem onto another, its extremely stressful for the relocated animal, there is the also the risk of spreading disease. The fact that these coons had to travel across a extremely busy freeway surely was a death sentence to many anyway.
I did not ask for animal control to come trap the raccoons on my property. They came to me as they were having numerous complaints about raccoons getting into trash, attics, garages, sheds etc. My coop is very secure and I lock the coop up each and every night. So the raccoons didn't bother me. I was actually shocked at the number of raccoons caught between me and my neighbor.
I have to register each year that I have chickens. The animal control officer has chickens as well (lives in another town) and knows I do as well as well the guy across the street, she often just stops by to talk chicken.
So she knew catching raccoons around coops would be a sure way to have a steady supply of raccoons to help reduce the numbers. Fortunately or unfortunately we do not have coyotes to help keep the numbers down. So like with much of wildlife these days man has to step in and be the predator.
I realize this a subject that touches nerves on both sides. I lean on the side of the most humane way is to dispatch the animals that are trapped.
