This is nothing more than an expression akin to an immature outburst. You may feel a flush of pleasure at the thought of retribution, but have you thought about how that is going to affect you? Also, reading through the comments, it's more than obvious that this is very polarizing, which in the long run is bad news for any community. Trust me, I've felt like standing on the side of the road with a bat waiting for next boy racer to go past at 8000 revs when trying to get my daughter to go down for a much needed nap. But reacting due to pent up anger is weak and damaging to everyone. That's what these buzzers represent, a unloading of pent up anger. Uncaring, menacing anger. To really spell it out, these buzzers are an automated, non-discriminating, non-lethal weapon. Is that what you want in your community?

Actually the point that most people miss is that this is not a case of age discrimination, it is a case of able bodied discrimination. (The deaf discriminating against the non-deaf). Given however that most teens are usually plugged into some form of electronic listening device Ipods etc(which consequently are proven to sizzle the delicate lining of the eardrums. I can't see this working. If councils are finding that young people are congregating around malls etc, then a more proactive approach might actually to provide alternative forms of entertainment for youngsters.

I think this is a great idea and if used appropriately they would be of huge benefit. Sold only to business, malls etc for legit reasons they could diminish some of the crime in our cities and loiters from corners. Any one with issue with this must condone such activity!

This is absolutely and completely a breach of basic human rights. I am a 19 year old student in my second year of a Law/Arts degree. I can hear the horrific sound made. How is it fair that I am discriminated against on the mere basis of age alone? I contribute FAR more to society than many people twice my age. Judge by what people do as individuals - not characteristics beyond their control.

@Scott #64 "when you were young", So when exactly was I young? Are you just guessing at some random time period?

"I bet you were not harassed by police and citizens for anyting you did". True - though it probably had something to do with being polite, respectuful, not annoying anyone, getting in the face etc, etc. If I did something worthy of harassment from the police or public then that is a result of my own actions, ergo my fault, not something to whinge ove how hard done by I've been. You reap what you sow.

"There were jobs for you to get money and things were very much less expensive". There are jobs now (duh!!!) and I notice students doing the same sort of jobs I did as a teen. Things were less expensive, but the pay was also lower to equal it out. In fact, to use your example of the movies, 1 hour at minimum wage can get you into most cinemas today whereas 1 1/2 hours of my minimum wage were needed, so if you follow that example the purchasing power of teens is higher than it previously was (the direct opposite of your statement).

"Your argument has little to do with what is going on right now". Well, apart from removing all the whining excuses that are put up as to why teenagers HAVE to loiter, get involved in crime etc, etc. Which actually makes them very relevant.

I have a small portable one of these units which I use to keep mosquitos away while working outside in summer... Seems to be a nest of them somewhere in the neighbourhood.

Cost me $10 at jaycars.

I don't agree with them at all. Having two small children - one prone to ear problems which this sort of thing would irritate I simply would boycott shopping in areas which choose to employ such drastic, abusive measures. It wasn't that long ago I was in my teens (mid 20's now) and I developed very quickly the attitude of "why should I respect you if you don't respect me?"

I pity the poor people who work in these areas that can hear this buzzing as well - makes for terrible customer service no?

Also please remember that in a few years when you are older these "pests" will be running the country and choosing (and working in) your rest homes. What seems like a good idea for now while you hold the upper hand will be your undoing.

Scott #64 - there's a thing called inflation plus jobs and money didn't grow on trees 20, 30, 40 etc years ago either. There was no free lunch and a much less materialistic society (i.e. a car, stereo, TV etc for a teenager was a rare occurance).

There were no skateparks, mountain bike parks, free concerts, playstation, internet, computers etc etc.

Also, you needed to be 20 to go to the pub (team policing units came and removed you with 2 warnings/fines then court appearance) where these closed at 10pm during the week and we were blessed with an extra hour to 11pm on Friday/Saturday (closed Sunday of course).

We had to make own entertainment (you know, stuff like sport, neighbourhood kids playing together, make own music etc) which didn't involve annoying the crap out of the surrounding community.

Otherwise you'd feel the consequence (from Police who would actually turn up or fellow citizens taking things into their own hands) rather than ending up on the naughty step to ponder where you want wrong or nothing being done because citizens don't want to risk ending up in court for sorting out little Timmy.

I thought it was illegal in most countries to (blatantly) discriminate based on age, gender, race belief etc.

#31 - Look up "Tinnitus"... Quickly.

The problem with people is people. If we just get rid of all the people then there will be noone left to either bother or be bothered by. Simple. Jim Jones had the right idea.
