Okay, let me step in and offer some advice.
1) You can search out individual PANs, but in general, these are like fireflies, or maybe ants, in the matrix, so they are usually are beneath your normal notice.
2) You can definitely go after one of the goons' PAN, but it is a risk/reward thing. or probably more of a effort/result thing. There will not be a huge combat advantage to doing so in most cases. Maybe you can shut down a gun for a second, or snarl up his cyberware, but that is after passes of breaking in and issuing commands, and that is ONE GUY. If they have a combat net of some kind, (not likely) you would have to go after that spider again. You could go after their comms, but right now they are shouting at each other and you can't do much about that.
3) Snow is a jack-of-all-trades with some good hacking gear, when the lead starts flying in a fight she should be shooting back, not fooling around to limited effect in Hot Sim.
4)
STOP TAKING ORDERS FOR WHAT TO DO IN THE MATRIX FROM A TEAM OF PEOPLE WHO YOU WERE TOLD BY FIONN WERE BARELY ABLE TO WORK THEIR COMMLINKS!
