The White House petition has garnered more than 88,000 signatures with a goal of 100,000 by September 12. The Change.org petition has more than 32,900 supporters with more than 2,000 signatures needed.

The Change.org petition, which was started by St. Louis native Kirk Siefert, hopes to send a message to the heads of the St. Louis County, Ferguson and City of St. Louis police departments. It reads: 

"Many continue to speculate what happened, and we may never know the truth," Siefert writes in the petition. "But one thing we know for sure is that the officer who killed him did not have a car dash camera or a body cam to record the incident -- a camera that could have prevented the incident or given us clear information about what happened.

"I've participated in the local demonstrations because I am so appalled by what has happened. These questionable police activities are unfortunately not new to many in this area. I've been illegally searched by the local police more times than I can count. Many of my friends can say the same. It's not right, and I won't stand for it.

"And I won't accept Michael's death taken in vain. That's why I am asking for the St. Louis City Police Department, the St. Louis City Police Department and the Ferguson Police Department to require police officers to wear cameras and record any interaction with the public at all times."
