The boycott may spreadthroughout the 43 million strong African-American community,which is estimated by Nielsen to have a buying power of onetrillion dollars. In the meantime, Missouri's governor, JayNixon, denied the possibility of presenting the case to a newgrand jury, standing firm despite protests throughout the U.S.and calls for a special prosecutor by numerous parties. OnWednesday, three nights after the grand jury's verdict,Ferguson had almost returned to normal. Only a few dozenprotesters challenged the snow and no incidents were reportedin St. Louis County, where the previous two days of violentprotests and looting had resulted in hundreds of arrests. Thesituation in the rest of the U.S. was also relatively calm withthe exception of Los Angeles, where police dispersed around 100demonstrators, who were throwing objects against officers andnearby vehicles, and made between 60 to 80 arrests. One ofthose arrested was a young man threatening officers with ataser gun, the L.A.P.D. stated. But the dwindling fire might beonce again be reignited by a video showing the last moments of12-year-old Tamir Rice, who was killed by a police officer inCleveland while holding a toy gun. U.S. media released thefootage and added audio recordings of eyewitnesses, who called911. In the first phone call, a man clearly states that theyoung boy was holding what was most likely a replica gun.However, the fact that the gun may have been fake was notmentioned in ensuing radio communication from policeheadquarters to officers near the scene. The CCTV footage showsa police car driving up and stopping near Rice, an officerstepping out of the vehicle and ordering the boy to drop thegun, and then the officer firing shots. (AGI).
