"When we walk the street and see video military style assault weapons on our streets at 9'o clock at night, that is not a sense of safety, that is not a sense of security and we can feel it," Alan Strasberg vice-chair of WeHo for the People, told Fox Los Angeles

The suspects fled in a Dodge Charger with cash. They were identified as Keymaurie Clark, 26; Briana Threets, 18, both Oakland residents, and a teenage boy and girl, both 15.
