So why did 7/7 use diy explosive?

• dogma1138 10y ago
  The attackers of 7/7 used TATP which you can make if you have sufficient knowledge of chemistry, you can also make RDX and PETN and even C4 at "home", this isn't "diy" explosives that kids make by mixing fertilizer and sugar over a hot plate, this is very potent stuff that requires quite a bit of expertise and experience to make. Because the UK might have stricter control over it? Because the attack was less funded? Hamas never had issues of manufacturing PETN and C4 for it's suicide vests. The brussels attackers used very high quality / commercial grade TATP and HMDT. BTW one of the main reasons to use peroxide based explosives like TATP and HMDT is because most "explosive detectors" look for a few specific signatures. TATP decomposes into hydrogen peroxide and acetone both of which are very common in cosmetics and various cleaning products which is a big problem as it would sound the alarm for every woman that just had her nails or hair done, so while it's technically not hard to detect practically it's virtually impossible to do so effectively unless you are screening very specific items. P.S. To anyone who've read this post welcome to the watch list :)
