Carseat safety

I hate that 2 of my nieces and an acquaintance don't know the rules or law. Here in USA we use chest clips so when I see that the chrstt clip is clear to the bottom or the damn straps are too lose I get highly irritable. You use it for safety people not use it to your own liking. My niece lowered the chest piece to take a pic of her son but he was asleep so she probably drove like that. Why on earth would you lower it to take a pic!? He is just as cute with it in the right position! My other niece had her 3 year old son forward faced and the straps were completely loose around his arms...her daughter's chest clip was one tug away from being on her stomach! And the acquaintance her son's chest clip was down to the buckle and the straps were loose! Like wtf people!? What happens if you were to be in an accident and the reason your child was hurt or died was because of your stupidity of not buckling/adjusting your child in the carseat right? Exactly so get shit right! A parent would want their child safe while in the car! I wish I didn't know these people or even be related to them -.-
