If it was tear gas, it tends to lay low and slowly rise so it could take several minutes for it to hit the detectors in a theater. Do they even detect tear gas? How high are the ceilings, and do they use rate of rise, ionization or photoelectric detectors. Each has its application, and aren't well suited to some applications.
BS. EOLR only detects open or shorted circuits. it doesn nothing to prevent bypassing a single switch, unless every switch is a home run. I used to teach new techs how to install alarm systems, and built an early central monitoring station.
I installed some in nursing homes that sounded an alarm if any door except the lobby door was opened to prevent walkaways in their dementia patients.
Point out how? This isn't covered by hindering prosecution which, at least the ones I am familiar with, require some active assistance in a case. Most have some flavor of (1) Harbors or conceals such person; or (2) Warns such person of impending discovery or apprehension, except this does not apply to a warning given in connection with an effort to bring another into compliance with the law; or (3) Provides such person with money, transportation, weapon, disguise or other means to aid him in avoiding discovery or apprehension; or (4) Prevents or obstructs, by means of force, deception or intimidation, anyone from performing an act that might aid in the discovery or apprehension of such person. Obstruction of justice also wouldn't fit this scenario.
Not hardly: In most jurisdictions, the right to remain silent allows ***any person*** questioned by police merely to refuse to answer questions posed by an investigator without giving any reason for doing so. (emphasis mine).
Oates said the gunman wore a gas mask and a ballistic helmet and vest, as well as leg, groin and throat protectors. He said among the guns was an AR-15 rifle and that the gunman used two gas canisters.
Nope. There is no state where a civilian has a duty to stop and give aid. Heck , last I looked there were only three states where a medical professional had a legal duty to render aid (outside of the regular scope of their employment of course) and these were so full of holes as to be practically useless. All of the states I looked at the website you suggested (ten before I got bored) stated very specifically what the requirements were of the DRIVER. Besides this is so far outside of the area we were discussing as to be in the Left Field PARKING LOT instead of merely coming out of left field.
None of which require you to talk to the cops and that is WAY outside the discussion of people at the Aurora movie.
I thought the thread had morphed to talking about leaving the scene of an accident when someone ran a car off the road after the driver of the other car had shot at them. I didn't see any exceptions in the law that allowed someone to not only leave the scene, but also not report their part in the altercation.
