Youtube Bodycam Channel Logo Design

I need a crisp, modern logo that immediately conveys “police documentary” and still looks sharp inside YouTube’s small circular profile picture. The design should revolve around a simple badge or shield motif—keep text secondary or omit it altogether—and use minimal, flat colours so nothing gets lost at thumbnail size.
The channel name is: Police Inquiries
Can play around with the idea of putting the name on a shield/badge/vest

Once the concept is locked in, please deliver:
• A master vector file (AI or SVG)
• Transparent PNGs, including an 800 × 800 px version optimised for YouTube

If you’ve created badge-style marks before, feel free to share them when you apply.
