Hello Nick,
The methods used by the police/authorities to catch criminals must advance to match the ingenuity of the felons who perpetrate criminal actions.
The freedoms we have to use fast cars, access explosives (fireworks), alcohol, etc have been abused by a significant number of people to the extent that their anti-social and criminal actions endanger or deprive others.
The UK has a relatively high density of populations per unit area, and that means like it or not most of us have to interact with other people who live here. Given that fact it genuinely helps to accepted norms of behaviour to minimise potential conflicts between the members of the population. It may be judged that our quality of life is not as good as in other countries, but one mans meat can be another's poison.
How do you resolve a conflict? Well it's far better to avoid it in the first place, but when one does happen, having an intervention scheme with clear working boundaries is very useful and effective. Our police forces are often saddled with this task, and in line with avoidance argument, they have to be proactive in curbing the irresponsible actions of others.
On of the inevitable outcomes of a conflict is that if the circumstances are reviewed often new regulations come into force to prevent the same circumstances resulting in a further occurrence. Here in the UK we are perhaps too ready to over react, but that is the fault of the population who put the politicians in to power.
I do agree that we are fenced in many ways, we can't construct or change a house without permissions, and other similar issues, but these matters have to be taken into account along with other factors, and the EU seems intent of eradicating parochial traditions. But if we wish to take advantage of the benefits of living in society we have to accept there will be some rules and boundaries to the individual actions we can take - we have to be considerate to others.
I do not condemn you for wishing to leave the UK , you believe you have found a freedom by living in France, but I think you will find that you are trading one set of rules for another - they may be better, who knows, and for how long?
