Honestly, I used to live in Tower Hamlets, another "immigrant heavy" area for three years, and never felt remotely threatened.

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.

I live in Tower Hamlets and witnessed an acid attack a few weeks ago, the attacker was white and the victims were white. I don't feel unsafe here either.
