Judges, juries and legislatures support the police overwhelmingly on this issue
Honestly, why? What possible legitimate reason do the police have for wanting to keep things (at least things outside the station) off camera?
For the legislator's it's simple. If you vote against cops, it will be used against you by your opponents and the police associations/unions will tell their members to not vote for you. As for the rest, most people are more likely to trust the word of a police officer over others. Unless the officer's behavior on the stand is just awful, he is almost always given the benefit of being considered more trustworthy.
Due to activities of privateers and pirates in the past, many nations have laws against armed merchant vessels being allowed in their harbors and/or waters. This is the reason the companies want devices that won't be considered weapons by these countries, Afterall, what good does it do to arm the vessel if it can't dock anywhere.
