First, God forbid you should ever need it.  I do.  For those who think it is cute to park in the handicapped parking because you are too lazy to walk a couple of feet - thank god you can walk.  Some of us can't walk or it is very very painful to walk.  We NEED those places available when we are looking for one.  We  may have to leave and go home without our groceries or medicine or something else we need because YOU took the handicapped space.  Even if you are "only going in for a minute" that is NO excuse.  Parking in handicapped parking when you don't need to is the ultimate in selfishness. 

New Hampshire has the right idea when it comes to abuse of handicap parking.  There anyone can take a picture of a violator that clearly shows them in the spot and that the spot is clearly marked and give it to police.  The picture is then used as evidence in court making it impossible to get away with.  I live in ny and here if you park in a spot without a permit you get a ticket but you have to go before a judge to respond to it.  i think its great so the judge can actually tell these people a thing or 2 and since traffic court is always busy the reprocussions cost alot more time than you could have saved by parking illegally in the first place.

Lets try reading for comprehension... As I clearly stated - so called powers of citizen's arrest DO NOT extend to violations or misdemeanors. Non Peace Officer arrest power applies ONLY to an OBSERVED FELONY. Thus - a private citizen detaining someone against their will because of a parking violation is committing the offense of KIDNAPPING which is a third degree felony. Texas law holds that using, or threatening to use, a motor vehicle in the comission of an offense constitutes "a deadly weapon" thus making it aggravated kidnapping. It also holds that if there are two or more persons being held it is aggravated kidnapping. It ALSO holds that if one or more of the victims is being prevented from performing a political or governmental function - like being a volunteer firefighter or EMS worker - the offense becomes AGGRAVATED KIDNAPPING which is a FIRST DEGREE FELONY.

So to answer your question YES, I would shoot someone who attempted to unlawfully detain me as is my right under Texas law. Penal Code section 9.32 specifically lists: "(B) to prevent the other's imminent commission of aggravated kidnapping, murder, sexual assault, aggravated sexual assault, robbery, or aggravated robbery." as a justification for shooting someone.

A NON Law Enforcement Officer detaining someone actually creates SEVERAL justifications under Texas law for shooting them. I already covered aggravated kidnapping. They also block your ability to retreat. If they are arguing with you threats are probably being exchanged. Furthermore 9.42 grants me the right to use deadly force to protect PROPERTY. "A person is justified in using deadly force against another to protect land or tangible, movable property" Such as MY CAR.

The law is VERY specific - per 14.01 unless someone is a SWORN PEACE OFFICER - they can only detain someone for a FELONY they personally observed. It doesnt matter if they would claim they were "detaining you for being illegally parked". First of all if they have two bullets in their forehead they wont claim anything because they are dead. LOL But, assuming they did claim to be "detaining me for being illegally parked" - thats an ADMISSION OF GUILT because illegal parking is NOT a felony. (Its not even a misdemeanor) It is thus NOT an arrestable offense, and detaining someone for it is KIDNAPPING.

So - dont worry about whether or not "people like me" should have a gun. Worry about people who are too ignorant to know the law, running off as half cocked vigilantes committing felonies against those of us who DO own guns and who are aware of when we may LAWFULLY use them. The idea that you need to be reacting to a threat to your life is a potentially fatal error. It doesnt have to be a threat to my life.It can be any of the named offenses, in defense of my person, in defense of my property, in defense of the person or proprety of a third person, in defense of the rights or liberties of myself or another etc...

Case in point - Joe Horn in Pasadena Texas saw two men committing a burgulary at his neighbors home. He called 911, and was on the phone with the dispatcher when he saw them leaving, He told the dispatcher "They are leaving Ill go kill them for ya" , put the phone down, went out, and fatally shot two men on his neighbors front lawn. HE COMMITTED NO CRIME because the law here in Texas specifically allows you to use deadly force: (9.42)  (A)  to prevent the other's imminent commission of arson, burglary, robbery, aggravated robbery, theft during the nighttime, or criminal mischief during the nighttime;  or (B)  to prevent the other who is fleeing immediately after committing burglary, robbery, aggravated robbery, or theft during the nighttime from escaping with the property;

Don't be "scared" of "loose gun laws" just DONT ATTEMPT TO DETAIN ANYONE FOR ANYTHING OTHER THAN A FELONY YOU HAVE PERSONALLY OBSERVED UNLESS YOU ARE A SWORN LEO OR YOU RUN THE VERY REAL RISK OF BEING JUSTIFIABLY SHOT.

 Frankly - even if you don't get shot or beaten into something resembling a wet prune, or run over with the car your blocking, youll still end up in jail when the cops get there... The cops don't like troublemakers. They are quite likely to "tune you up" if you escalate a private property parking lot infraction that wasnt even their problem in the first place into an aggravated kidnapping, unlawful restraint, terroristic threats, disturbing of the peace, etc.... Cops like NICE QUIET DRAMA FREE DAYS. They despise mouthy drama queens, and people who try to do their job.
