There is no evidence linking the use of drugs to the crime, although it's probably true that there's a growing drug problem in much of the world, as even there is in my small city of Kelowna. This may be related, but there is no evidence to support that.
With regard to the Jewish community or anti-Semitism, there have been cases in the last couple of years where synagogues have been raided and so forth. The government claims it has had no role in this and that it has investigated.
The government has been very harsh on aspects of Israeli foreign policy, which is distinct from anti-Semitism but some have drawn a connection between the two. There is, I'm telling you, no evidence linking the government to anti-Semitism but some have drawn the link based on the violence happening at synagogues and a policy on the part of the government that is highly critical of Israel.
