  he $B(E2,2^+ \rightarrow 0^+)$ transition strengths of the T=1 isobaric
triplet $^{70}$Kr, $^{70}$Br, $^{70}$Se, recently measured at RIKEN/RIBF, are
discussed in terms of state of the art large scale shell model calculations
using the JUN45 and JUN45+LNPS plus Coulomb interactions. In this letter we
argue that, depending on the effective charges used, the calculations are
either in line with the experimental data within statistical uncertainties, or
the anomaly happens in $^{70}$Br, rather than $^{70}$Kr. In the latter case, we
suggest that it can be due to the presence of a hitherto undetected 1$^+$ T=0
state below the yrast 2$^+$ T=1 state. Our results do not support a shape
change of $^{70}$Kr with respect to the other members of the isobaric
multiplet.
