New Orleans officials and cultural advocates say the Mother's Day parade shootings that left 20 people injured won't spell the end of second-line parades, the local tradition that celebrates the city and its people.

Police this week arrested two brothers and charged them with 20 counts each of attempted second-degree murder. They're accused of firing into a second line, scattering the crowd and wounding 19 with gunfire. One person was hurt fleeing.

In a second-line parade, watchers of a street procession of brass band musicians and elaborately clad marchers often join in, forming a second line of marchers.

Second-line parades have been around for generations as part of Mardi Gras and other holiday celebrations, and are perhaps best known as a feature of the city's famed jazz funerals.
