Correct me if I’m wrong but I’m sure this is incorrect. I didn’t want to piss on anyone’s chips but I’ve looked into it :
transwoman retain male patterns and rates of violence even after transition
So I’m not here to tell you transwoman are saints. But this may be useful - assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/567053/prisoner-transgender-statistics-march-april-2016.pdf
So of the 70 inmates who said they were transgender in prison in 2016, 52 reported their gender as Male, 14 as female and 4 did not say. Strange isn’t it that fair play for woman haven’t mentioned this when waving about the statistics 
The Swedish study I presume you’re refering to is based on a case study in the period of 1973-1988. The author of the study herself said this:
The study as a whole covers the period between 1973 and 2003. If one divides the cohort into two groups, 1973 to 1988 and 1989 to 2003, one observes that for the latter group (1989 – 2003), differences in mortality, suicide attempts, and crime disappear. This means that for the 1989 to 2003 group, we did not find a male pattern of criminality. The difference we observed between the 1989 to 2003 cohort and the control group is that the trans cohort group accessed more mental health care, which is appropriate given the level of ongoing discrimination the group faces.
The study itself, if you click on ‘results’ on the article says this - Transsexual individuals were at increased risk of being convicted for any crime or violent crime after sex reassignment (Table 2); this was, however, only significant in the group who underwent sex reassignment before 1989.
This is the table within the article which also proves this.- journals.plos.org/plosone/article/figure?id=10.1371/journal.pone.0016885.t002
Unfortunately, false statistics don’t help anyone. And given it’s one that’s often trotted out on here, I’d have thought you’d all looked into it more. Took me 5 mins on google to find this.
