These people you refer to are not there to stop photography, They are there to prevent an assortment of things like theft, personal injury and a few others. Nine times out of ten they really don't give the back side of a rat if you snap off a few shots of a building, however once you step within the property line the company who hired him is responsable for what ever happens to you, thus by technicality they are obligated to have you removed from the premisis.
I am currently a Child Care provider and I am the first one step infront of a lens I feel is in the wrong place at the wrong time reguardless of body.
As you said there is situational reactions, when in large groups of children I see no reason for some one who showed up with with their kids to snap away at who ever they feel like with what ever they want. At the same time though with any groups some one who shows up out of no where with a 80-200 macro zoom and no kids in tow, is not going to like me at all.
I am the kind of person who will tell some one to change their lens or leave, and if they refuse, the children I am entrusted with are gone no two ways about it. Shoot with a short lens I can tolerate but anything giving anysort of close up I will not stand for.
Taking photographs of children is not the issue, it's those who take the opertunity to get innapropriate shots of children wile they play. It is very easy to get some shots thet could be of sexual interest to pedophiles wile children are playing, trust me I've thrown away dozens of them taken by shere accident, both male and female. If one sets their mind to it the results could be devistating to the one in the picture. That is the source of the fear around it. This is why I do not allow people I do not know nor can validate their presence to use long lenses regardless of their intentions. To be quite frank I don't care how skilled the person is, they are not going to get a good upskirt shot with a 50mm from 40 yards.
At the same time I have no qualms with parents using stuff like that regardless of who they're taking pictures of or even using them my self as I am confident parents intentions are fine.
Hey, I understand exactly where you are coming from. But this opens up another can of worms, doesn't it. And that is "intent." What are the intentions of the photographer- why is he taking those photos, what will he do with those photos, if anything. And that is a really gray area for law enforcement. Here is a story I posted a few months back about this very issue. I think in this instance, you see a perfect example of the old saying "give 'em and inch and they will take a mile."
Here is an example of when well intentioned laws are misused by authorities. In 2003, I believe, Texas passed a law prohibiting unauthorized photography inside locker rooms, dressing rooms, etc. The law was basically written to stop pervs from taking photos with cell phones and so on and then posting the shots on the internet and other places. However, the law was so vaguely written, that soon, prosecutors around the state began extending the scope of the original law to "catch" perverts in public taking "questionable" photos.
In 2005, in Southlake, Texas, a very affluent suburb of Dallas, Lewis Vogel was arrested for shooting innapropriate photos at an Octoberfest celebration in the town square. Several ladies at the event noticed him shooting photos of, what they said were pictures of nothing but young girls. The ladies approached a couple of police officers and told them about it. The cops asked Vogel if they could see the pictures. He showed the photos to them on his camera and they promptly arrested him and confiscated the camera.
The Southlake police department held a press conference a few hours later detailing the arrest of Vogel to the media. That evening, the story ran on every evening TV newscast, featuring Vogel's name. Vogel had no prior criminal record. Not even a ticket. Nothing. He explained to the authorities that he was testing out his new camera and he had shot several photos of pretty girls in the crowd, as well as other things happening at the event.
Vogel was released on bail. A few days later, another press conference was held in which a city attorney announced that all charges against Vogel had been dropped and an official apology was made to Vogel. The attorney said, that after reviewing the photos, there was absolutely nothing illegal about his activity.
Of course, the damage to Vogel's reputation had been done. I believe that Vogel later filed a multi-million dollar lawsuit against the City of Southlake.
This is what happens when you have vaguely written laws and then ask the police to enforce these laws. A lot of times, publicity seeking politicians pass band-aid type laws instead of dealing responsibly with the real problem.
This is what worries me. These are the type of things that politicians love to get their teeth in because it makes them appear tough on crime, etc.... when in reality, it is ridiculous and absurd.
And you know, I don't know what the answer is. Of course, everyone wants to protect children, but somewhere, somehow, we have got to hit a middle ground and reign in this hysterical fear that a boogeyman with a camera is hiding around every corner, in every bush. I wish I knew the answer.
