Cuts to the region’s federal homeland security funding could jeopardize a plan for $25 million in communications infrastructure to allow emergency responders from one part of the area to understand what’s happening in another, local officials say.

Building the communications infrastructure would let the region add several applications that were in its security plans. It would allow law enforcement agencies to check warrants and fingerprints from other jurisdictions, said Edward Reiskin, Washington’s deputy mayor for public safety.
