When Fargo is in the restroom and puts the device in his inner pocket, the light is clearly seen through the cloth but not in subsequent scenes.
When Fargo's heart was stopped to turn off the force field, a defibrillator was used first. Defibrillation is used when the heart rhythm is irregular, not when it's stopped. Allison, as an MD, would know better than to use the defibrillator before starting CPR as chest compression is the accepted way to start the heart.
The reflection of the boom mic and operator are visible in the passenger window of Carter's vehicle (16:33 mark)
Many of the staff in Global Dynamics address Allison Blake as "Ms. Blake," when they should know that as an MD her appropriate title is Dr. Blake.
