Using Night Vision in Law Enforcement Vehicles
In the air and on the ground, the ability to see in the dark while mobile enhances crime fighting capabilities and makes officers safer.
Thermal systems such as this FLIR Systems Scion PTM cannot 'see' through glass. So users must roll down the window or use an externally mounted system.

What does the Supreme Court ruling in Graham v. Connor say about police using force?
Envisage Technologies
The Supreme Court held in Graham v. Connor (1989) that whether departments are liable in civil "use of force" lawsuits depends on the objective reasonableness of the officer's actions given the particular facts and circumstances of the incident.

What is spoliation and how can we avoid it?
Envisage Technologies
Spoliation refers to the failure to preserve relevant evidence.  In some jurisdictions, it can serve as an independent basis for a lawsuit, but most commonly it results in a jury being instructed to make an adverse inference against the spoliator regarding the contents of the evidence.
Training
Can we just keep our records in a record book?
Envisage Technologies
Sure you could, in much the same way that your department could be using battle axes or bows and arrows instead of guns to defend themselves.

Q: Can a facial recognition system identify two people who are twins and who are dark-skinned of African descent?
Vigilant Solutions
Even though identical twins are sometimes distinguishable by the human eye, facial recognition algorithms will not be able to pinpoint and distinguish the physical traits between each of them.
Technology
Does a 150-pound weight gain/loss still produce a hit due to changed recognition points?
Vigilant Solutions
Although facial recognition algorithms look for similarities when returning candidates in a search, significant facial changes such as weight gain or loss do affect matching accuracy by reducing the matching accuracy overall.
Technology
Can you use uncontrolled images like CCTV stills, ATM images, social media, etc.?
Vigilant Solutions
Images that are not taken in a controlled environment, like CCTV, ATM or social media pictures, are still usable thanks to advances in facial recognition technology.
