There’s been too many shootings for them NOT to release this information.
There have been over 16 shootings there should at least be way more information out there. As I said there is a political motive to downplay these shootings as the highways are central to Atlanta’s economy.
If you want to be an amateur investigative reporter then you need to print out every article you read, look up social media contacts for the victims, see if you can reach out to their families, contact the police departments involved and obtain what public information you can regarding all these individual incidents.
You might have to pay the department $5, 10,15, 20 or even $50 for the information but you can obtain the information and copies of reports as well as audio of any 911 calls. YOU can do this as a citizen, you don't need a lawyer. There's some information they may without or not disclose, due to any open or pending investigations, but you can obtain something.
Document everything.
Document names, dates and times of everyone you contact or even attempt to contact.
You've got some work to do. Either you'll find something big or have whatever fears or concerns you have resolved.
It's on you though.
