Question How should I handle this?

Earlier today I saw something that made my heart skip. We pulling into our local $tree store next to a white Honda Accord. Nosie me, I looked into the back seat to see what kind of car seats they had if any. And to my shock I saw what looked like and 18 month old in a Cosco Explorer seat without the cross bar. And the child didn't even look seatbelted. (The child just bairly filled the seat) Trying to keep my cool I said 'excuse me, I wanted to let you know that the way your child is sitting in the back seat is illegal and I don't want to offend you, but that is not safe. You can go to your local fire department and they should be able to help you out.' I didn't want to create a scene, so I continued into the store and did my shopping. When I was at the checkout I saw them walk in and heard the child babbling, not really making any sounds that sounded like words. My heart was sinking, but I didn't know how to handle this situation. After I got back into our van I ask my husband if he heard them say anything. He said 'they finished smoking and were taking and laughing, then went into the store.'

My question is how do I handle this and is it too late? I did write down the plate number.

Let it go

You never know how someone will react if you say something. There are horror stories regarding people doing crazy things in similar instances.

The police *might* do something, but that's unlikely

It sucks. It gets a smidge easier with time.
