Covertly tipping your partner to danger
When you spot the weapon, say something to your partner and call them by your name. This will tip your partner to the fact that something’s wrong without tipping off the criminals before you can act as a team and get them controlled. You can discuss what the threat is once you have the situation safely under control. If this buys you a second, it is worth it. If you yell “Gun/Knife/Dope” it gives the criminals a chance to react at the same moment as your partner. Take any advantage you can. Be safe out there brothers.
