Lance Chambers:
Items from Van if possible:
2 Pistols from Swat Van
30 more ammo for each from Swat Van.
Initiative Taser Rifle from Swat Van if there.
Bowie Knife from Swat Van if there.
Hand Radio from Swat Van.
You can have all that except the bowie knife, vamp cops aren't fond of knives.
You still have the taser rifle Aaron gave you, although we'll say there are a couple more on the van if you want to grab a spare or two in case the one you have gets lost.
