Petitions are important, because if a lot of people sign them, then it shows that a lot of people care about this topic. And the more people supporting the topic, we get better chances for topics to be at least somewhat solved.
There are a lot of petitions about Black Lives Matter on this site, but there is also a large variety of different topics.
"A division of the Louisville Police Department performed an illegal, unannounced drug raid on her home. Not a single officer announced themselves before ramming down her door and firing 22 shots, shooting Breonna 8 times, killing her. Not only were the police at the WRONG HOUSE, but the man they were looking for had already been arrested earlier that day."
"Pervis Payne is facing execution December 3rd. Payne is 100% innocent. They haven't done a DNA test on the victim which would prove his innocence. Payne is a disabled man with an intellectual disability.
He was 20 years old when he stumbled upon a murder scene in June of 1987. He was shocked and tried his best to help the victim but he was mistaken as the attacker. He described it as the worst thing he's ever seen in his life."
One of many community petitions for the BLM movement can be found here.
More petitions can be found here. There are some Black Lives Matter petitions, such as justice for George Floyd. However, only about 5 petitions on the website are actually about BLM.
Here is a petition page that has a single petition for Black Lives Matter, however it is for the whole of Black peoples justice, not just one person.
