Chilling effects, prior restraint, and the RKBA

[pauamma]

Chilling effects and prior restraint are most often associated with free speech issues, but (inspired by an IRC discussion of the recent CT bill mandating weapon registration), I've been wondering whether they had been applied to weapon registration requirements as well, or could reasonably be. (Note to maintainer: can you add tags for topic: us: 1st amendment and theme: chilling efects ?)
