How barricaded incidents are handled
In situations like this, police agencies typically focus first on containment and communication, bringing crisis negotiators to the scene before considering the use of force. Specialized tactical units, when they are called in, coordinate with negotiators to protect bystanders and first responders, according to a tactical guidance paper. As outlined by LAPD Tactical Concept No. 18, patience and negotiation are central to resolving barricaded suspect incidents while minimizing harm.
What residents should know
Officials advised people to stay out of the area while the response was underway, and drivers in downtown San José were told to expect delays and use alternate routes when possible. For emergencies, residents should call 9-1-1. For non-emergency tips or information tied to the incident, the San Jose Police Department lists (408) 277-8900 as its non-emergency line, as noted on the San Jose Police Department communications page.
