Defense of "Impossibility of distant indirect measurement of the quantum   Zeno effect"
  Recently, Wallentowitz and Toschek [Phys. Rev. A 69, 046101 (2005)] criticized the assertion made by Hotta and Morikawa [Phys. Rev. A 69, 052114 (2004)] that distant indirect measurements do not cause the quantum Zeno effect, and claimed that their proof is faulty and that their claim is unfounded. Here, it is shown that the argument given by Wallentowitz and Toschek includes a mathematical flaw and that their criticism is unfounded.
