Neither have the demographics in these areas "changed" much. The east end of London has had a large immigrant population since the 1970s and arguably since the 1700s when the Huguenots arrived from Northern France.
The most danger I was ever in was when they discovered an unexploded WWII bomb next to my flat ("The parties we've had in here, if it was going to go, it would have by now").
Acid attacks are so incredibly rare (350 last year) that any increase at all in them is going to represent a large statistical increase. If I had to hazard a guess as to why acid attacks were on the increase, it's because carrying a knife carries with it the chance of losing your own life as well and a life prison sentence if you kill someone. It's also (marginally) easier to argue that you're carrying a corrosive substance innocently than if you're found with a gun/knife. You are still 70x more likely to be involved in a knife attack than an acid attack.
Asking why immigration and changing demographics has caused this presupposes there being a racial motive at all. Explicitly asking for evidence which supports your theory suggests you've already made up your mind.
Why it is a convenient weapon? Cheap to buy and readily available, easy to carry around in a bottle and completely legal(I think that part is changing).
Some Immigrant neighbourhoods being poor is nothing new, and poor neighbourhoods suffering from criminal activities is again nothing original. Again, these neighbourhoods are not new and the immigrants hadn't moved there recently. So it doesn't look like some kind of immigrant critical mass was reached and they start throwing acid.
So no, you hadn't uncover a mystery or spoken the words that nobody dares to.
My guess would be that someone used acid for their criminal activities and had positive(from offender POV) results and it spread out as MOW.
Seems highly likely to me this is a result of improved and increased pressure over knife crime, pushing criminals into new methods, alongside increased exposure to the idea of acid attacks from news.
Something tells me its not a coincidence.
Yes, that something being racial prejudice. Sad to see this attitude rife on HN.
You forgot to call me a "Nazi" and "bigot" and "facist" and all the other things you ANTIFA folks call those who have different opinions than yourselves.
How many more alt-right talking points can you squeeze out? Your reaction is so amusingly predictable, it’s sad to see someone so programmed to dullness.
But most of the attacks in the U.K. are random and are often connected to robberies or gang violence. Many of the perpetrators are in their teens."
I don't follow how we can lay the responsibility for this increase in attacks at the feet of people from the Middle East coming to the UK if the motives are so different. The method is the same but the motivation is fundamentally different.
Perhaps the simpler explanation -- that it's a method of assault that is easier to get away with, has lighter sentences if caught and is not illegal to carry the weapon -- is more likely.
