I just came back from visiting my mother, about 130 miles away. On this trip
I had a Kahr 9mm pistol and two full extra magazines, a 12 gauge Benelli M 90 shotgun with about 25 rounds of various sizes of buckshot, a .30-06 Winchester Model 70 ("sniper" rifle?) with 30 rounds of 150 grain bronze point, a Busse Battle Mistress, a Busse Active Duty, a Bladerigger Arch Angel II, a 4 inch Cold Steel clip point voyager, a Spyderco Native, a Case Sodbuster, two large size contractor grade garbage bags, duct tape, and a three cell Maglight. This time of year in Alabama, you never know when a deer hunting opportunity might come your way, plus when I go to the country I like to take some toys.
The items found in the guy's car, absent the clearly criminal intent inherent in his conduct, would not or should not be alone grounds for suspicion. His behaviors, however, clearly were.
