Zimmerman Supporters Challenge Pro-Trayvon Protesters in Houston

Now we hear from both sides

HOUSTON — Dueling marches here Sunday in support of and in opposition to the verdict in the George Zimmerman case led to a massive police deployment, heated face-offs but no violence, police said.

For many, the protests showed that although the controversial court case may be over, the debates it sparked concerning racial profiling and "stand your ground" self-defense laws have only grown, leading to

demonstrations this weekend in more than 100 cities in support of 17-year-old Trayvon Martin.

Zimmerman, 29, a neighborhood watch volunteer, was acquitted this month by a Florida jury in the fatal shooting of Martin on Feb. 26, 2012. A Justice Department inquiry into the case is still underway.

Unlike in other cities, Sunday's protest here drew several hundred Zimmerman supporters who, though far outnumbered, were outspoken and determined to be seen.
