“Aber wir müssen akzeptieren, dass die Zahl der Straftaten bei jugendlichen Migranten besonders hoch ist”
which translates to:
“We have to accept that the number of offences by young migrants is particularly high”
This is Merkel not denying the numbers. If the clip was longer, you would very likely hear her say that this problem must be addressed.
The way the quote is translated, makes it appear that she is stating that crimes by immigrants simply must be accepted.
