Yes. See below.
But, the fact remains, four adventures of the AP tie into bad things happening in the small town of 1000+ people in a sparsely populated region that is attacked by goblins [sblock]serial killers, mutant goblins, ghouls, giants, cultists, the sandpoint devil[/sblock], and many more events. A disproportionate amount of bad is happening to a tiny town. And when you start looking at the random encounter tables and other side events happening in and around the town, there is a LOT of dangerous stuff crammed that close to settlement.
Additionally, the adventure banks on the PCs being the heroes and not running to some of the higher level NPCs for help. Like the sheriff (level 4 fighter), Shaelelu (level 6 fighter/ranger), and Ameiko Kaijitsu (level 3 bard/rogue), and letting them handle the threat of the goblins at Thistletop. Or not having the players run off to Magnimar for help against the numerous gathering goblin tribes that can be perceived as outnumbering the PCs. Heck, when investigating the murders in Magnimar, the adventure pretty much assumes the PCs are going to just investigate the high profile murders on their own and not pass their evidence to the local constabulary, despite Sheriff Hemlock already going to them for assistance once.
None of this compromises the quality of the adventure. Because the PCs are heroes and unwilling to "turn their investigation over to the Feds". It's just a common element of adventure design that PCs could get help, but almost never do.
