London Police To Wear Video Cameras In Pilot Project

canthusus Re:Can't turn them off? (152 comments)

You need to turn them on first...

From BBC article: "The force said officers taking part in the pilot must comply with guidelines about when cameras are to be used, but that they will not be permanently switched on."

canthusus Mark or analyse? (45 comments)

Or forget about the complexities of a marking scheme that will only be found on a subset of dumped products, many of which will predate any mandatory scheme. Instead, how about analysing the trash on-the-fly? If only there was a cheap open source chemical analyser available...

canthusus Re:No, actually. (1188 comments)

If you do not, and you maintain that you can't compare the statistics, then there's no way you can say crimes are higher in the US either.

I don't think I ever claimed that crimes are higher in the US.

There is an objective reality. There are a certain number of crimes that occur in both countries each year. One country is more crime ridden than the other, even if only by a fraction of a percent. You assert we can't tell the difference.

No. I assert that we can't tell the difference from those sets of figures.

Again, if you can find a different report that you find suitable for comparison from either country, please post it and I'll read it. We can then discuss it.

Tell you what, why don't you start at the UK Stats Office:http://www.statistics.gov.uk/hub/crime-justice/crime/crime-trends/index.html. They explain when recorded crime is a better measure, and when a crime survey is better. If you look at the trend graphs, you can immediately see that in 2007/8 BCS reported 10 million incidents, while Police figures show only 5 million recorded crimes. Surveys report more crimes than police record. Or look at the Home Office report for 2007/8: http://www.homeoffice.gov.uk/rds/pdfs08/hosb0708.pdf. Burglaries 300,000 according to police, 800,000 according to the survey. Measuring different things in different ways.

You ask in another post "If you are unwilling to consider why methods are picked, what implications those methods have, and what institutional goals are supported by those methods and implications, then you are the essentially the most likely to be bullshitted by statistics.". I suggest that this comment applies very well to the OP who tried to compare US recorded crime figures with UK victim survey figures. And to anyone who gullibly believed the comparison actually meant anything.

canthusus No, actually. (1188 comments)

I invite you to poke around the official numbers for both the US and the UK and make a counter argument.

Those statistics are measuring quite different things, and cannot be meaningfully compared.

The US figures are offences recorded by the police.

The UK figures you give are from the British Crime Survey - a survey of people, who are asked if they have been victims of crime. Such surveys always give much higher figures, for a variety of reasons.

In many ways a crime survey gives more useful numbers, as it measures victims rather than crimes, and isn't subject to recording differences. But the two really cannot be compared.

US Forgets How To Make Trident Missiles

canthusus Re:Securing peace by getting rid of the US (922 comments)

Given how many wars were fought in Europe in the 19th century and the first half of the 20th, and how many in the second half of the 20th, something must have happened. If it wasn't US troops, what was it? Why were the horrors of WWII enough to convince Europeans not to fight each other, when the horrors of WWI weren't?

That's just so bizarre it's hard to know where to start...
Apart from the fact that Europeans still are fighting each other in a number of conflicts, even if there had been no armed conflict at all in Europe since WW2, why on Earth would you assume that US presence caused that? Especially given the conflicts that have occured when US troops have been present.
OK, "if it wasn't US troops, what was it?" how about:

  • invention and development of the computer
  • widespread use of television
  • foundation of the United Nations
  • the invention of the bikini
  • the Roswell incident

All of these also happened around the end of WW2. And are as likely as your suggestion. Correlation does not imply causation.

Harnessing Slow Water Currents For Renewable Energy

canthusus Re:Secondary effects? (113 comments)

IANAFM also, but yes, I'd expect to see slower water, as we have extracted energy from it. With care, this need not be a bad thing - for example, groins have been constructed on parts of the Thames to slow the water near the banks, encouraging scour of the main shipping channel. Erect a vortex generator instead of groins and you can control flow and generate electricity. Downside is it may become too successful, and the silting could interfere with operation.
