From Guns.com:

The bill is entitled H.B. 49, “Firearms Revisions,” and states “… in the absence of additional threatening behavior, the otherwise lawful possession of a firearm visible or concealed” would not constitute a violation of Utah’s various criminal provisions and statutes.

In short, if the bill is passed law enforcement can’t arbitrarily charge one with a crime for lawfully carrying a firearm – as in the case with Taylor.
