LA bomb squad ‘grossly miscalculated’ weight of fireworks in huge explosion

Los Angeles police department and FBI are reviewing protocols for detonating explosives after incident left 17 injured

Los Angeles bomb technicians grossly miscalculated the weight of homemade fireworks last month when they detonated them in a containment chamber, likely causing a catastrophic explosion that injured 17 people and rocked a neighborhood, the police chief said Monday.

Police chief Michel Moore said five members of the department's bomb squad have been removed from field duties as the investigation continues. They could face discipline.
