But scientists with the University of Georgia and Oak Ridge and Argonne national laboratories are looking at new family of crystals they say glow different colors and hold the key for letting white LED light shine in homes and offices as well as natural sunlight."

It is bribery if the money is used to pay blackmail to a mistress.

Even if the mistress is a paid agent of the politician's opponents, and the blackmail payment is to outbid them? Two (or is it three?) wrongs don't make a right IMO, just wondering about other people's views on using the money counteract someone else's dirty tricks/use of bribe money...

Exactly; saying "X has increased since Y, therefore Y caused the increase in X" is simplistic nonsense because it ignores previously existing trends and other confounding factors (for example, I'd say that the consistent correlation between arrests for amphetamine possession and assault rates suggests a greater probability of a direct causal link, but that doesn't make it true).

I'm not sure it's correct to say the 1996 ban on semiautomatic long arms* didn't do anything: the previously existing trend suggests there should have been a few mass shootings since then, but the number dropping to zero overnight could also be explained by dealers voluntarily tightening up their practices or some other factor, so that's a "maybe". The wider ramifications for other violent crime are even harder to quantify, since semiautomatic long arms aren't typically used for self defence...not even the criminologists and statisticians with access to finer grained data and years to study it can agree, I doubt there's greater expertise here. And trying to relate it to the US, which has a completely different attitude to guns and historically far higher ownership rates, is probably futile.

*Handguns have been restricted since 1901 in New South Wales and for similar times in other states. It hasn't been legal to carry a gun without a valid reason (which doesn't include self defence) anywhere in Australia for over 100 years, so it's improbable that the 1996 ban on semiautomatics made any real difference to crime rates at all.

The Australian experience of an increase in forcible rape after guns were banned.

False. There was no appreciable increase in the three years after the ban came into effect. There has been an increase since, however that follows a trend line that started before the gun ban, so there is no correlation between the ban and the incidence of rape.
