My recommendation is to do more follow-through with your idea and do less talking. If it's such a good idea why not develop it, put it in writing, and send it up the chain of command? Even if it's someone else's idea, you can help someone else find a way to push it through.
I'll give you an example. While in charge of our agency's motor unit, I wanted to place short-barreled rifles somewhere on our motorcycles. I thought it made sense since motor units are so versatile. They can drive practically anywhere and go through just about any terrain. They are also one of the easiest units to free up in case of an emergency.
Historically, most motor units either don't carry a rifle or they carry it mounted in the open. Since neither of these options fit the model I was trying to develop, I discussed it with my unit and came up with a game plan. We used one of our SWAT team's short-barreled rifles as our standard. We designed a special bracket that incorporated a mount already used in our vehicle maintenance section's inventory. We also agreed that it needed two separate locking systems: the saddlebag and the rifle mount itself. We then began figuring out how to make it all work together and conceal it within a saddlebag. Having an idea was not enough; we had to prove it was viable as an option.
Once that was done, I wrote a proposal, took pictures of our prototype, and pitched the idea. The proposal included material and personnel cost factors as well as several versions of how we could build the new rifles, and outlined a timeframe for the project. Our hard work paid off and we got approval to implement the idea. Each motor officer, including those cross trained, became police rifle certified and now carries an M4 short-barreled rifle in their saddlebag.
If all we had done was talk about it nothing would have ever happened. If you have a good idea, figure out the details, write a proposal, and submit it. It's the only way your idea stands any chance of going anywhere.
