Frequently Asked Questions

Is Glendora Police radio encrypted?

Yes. Glendora Police uses P25 DES-OFB encryption. This agency encrypts all of its radio communications, including routine dispatch. The public, journalists, and even other first responders can't monitor its activity.

Can I listen to Glendora Police on a police scanner?

No. Glendora Police has fully encrypted their radio communications using P25 DES-OFB. No consumer scanner can decode encrypted transmissions.

Why did Glendora Police encrypt their radio?

The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.

Can Los Angeles County reverse the encryption decision?

Nothing technical prevents it. Glendora Police operates encrypted because someone decided it should, and decisions of that kind get revisited when councils hear sustained, organised pressure rather than isolated complaints.

What can I do about Glendora Police encryption?

File a FOIA request for Glendora Police's radio recordings and encryption-decision paperwork, then show up to speak at a council or commission meeting. Find other residents or journalists in Los Angeles County who want the same access — state legislation requiring public radio access is the longer-term fix, but organized local pressure is what usually moves the needle first.
