To think 'there's no law against it' isn't always a good reason to do something

[Summerbreezing]

Just see it all the time:

Smoking in a crowded bus shelter on a rainy day?
Why not, there's no law against it?

Letting your kids play noisy games on the communal Green at 11 and 12 at night?
Why not, there's no notice up to say they can't.

Letting your dog run up barking at strangers in the park?
Why not? There's nothing in the park rules to say dogs have to be on a lead.

etc etc etc.

Why does there have to be a 'law' or a 'rule' for everything? Can people not just exercise common consideration sometimes?

Look on the bright side. There is also no law against you calling the perpetrator an inconsiderate oaf.

YANBU. And then, when laws have to be made because of the knobs who can't just use consideration and common sense, it is those knobs who start moaning about the 'nanny state.'

HMM, it's one of those phrases, like "PC born mad" that makes me think the person has perhaps not got a great grasp of nuance

The other thing is the attitude that 'I've paid to be in the restaurant/swimming pool/soft play centre, so I'm entitled to let my child scream/stand in the middle of the pool chatting/ignore my toddler hitting another child while I relax with a coffee.

Also "I pay my taxes"

The flipside of that is the perennial AIBU favourite: 'Of course you can take your baby to the no-children-please wedding, legally they have to let you and your baby into the church! You should just turn up - they can't stop you!'

Just taking your examples:

Depending on just how enclosed the bus shelter is, it might just be deemed enclosed enough for the ban on smoking to apply!

There are laws regarding noise pollution and it doesn't matter what exactly is causing the noise. So, depending on circumstances such as volume, frequency, duration, proximity to your house / other houses etc.. Children screeching like banshees at wildly unsociable hours may actually constitute a noise nuisance which the council might be able to do something about!

Dogs in a public place (such as a park) must be 'under control' at all times.
My dogs are extremely well trained and on the rare occasion I have cause to take them to somewhere where there are other people (such as a public park), they walk / play within about 20 - 30 yards of me at all times and come / sit upon whistle , first time, every time. And as such do not require a lead to be deemed 'under control' - they're more obedient than most people's toddlers. A dog running up to someone in a park , barking or not, does not sound to me like a dog that is under control. There are laws to deal with them. At the very least they should be on a lead, if they look aggressive then a muzzle should be used.

Sorry, I'm just being pedantic to show that if you think most situations though then you will find that there is probably some sort of law or bylaw that is applicable to help you deal with a given situation.

I do however, agree with the spirit of your post!!

It is illegal to smoke on TFL property, that includes bus stops, train platforms, in tube stations etc. I find it very rude especially when people start to smoke near groups of young children.

However, to the rest, YANBU :-)
