THE episode of Raja Ehsan Aziz shows that the War on Terror, or at least its connected investigations, are being conducted by the Pakistani agencies through traditional police methods, whereby if an accused or wanted person has escaped, relatives are picked up, even if totally not associated with the charge in any way. An example has cropped up where the person wanted is Ahsan's son Umar, whom the investigating agencies are seeking in connection with Jawad, a driver in whose name was a SIM, which was used in the course of the attacks on the Parade Lane Ground Friday congregation in Rawalpindi and on Moon Market in Iqbal Town, Lahore. Because his family said Umar had taken his books and disappeared, probably in the International Islamic University, the investigation agencies tried the time-tested technique of arresting his father instead, and Raja Ehsan was picked up on Wednesday. This ignores the fact that ought to determine everything: that Raja Ehsan is not wanted in any other connection. This ancient police tactic has apparently been adopted by the investigation agencies which are now pursuing the War on Terror so enthusiastically. That there is no charge against him counts for nothing, let alone his being a retired professor of International Relations at Quaid-e-Azam University, where he taught after a career in the Foreign Office. His wife is an ex-MNA of the Jamaat Islami, though the family is now linked to the Tehrik-e-Islami, a Jamaat splinter. None of these should call for any special treatment, but equally, none of these justify his arrest, or indicate that any charge should be laid at his door. The tactics leading to his arrest may have originated in the practices that make up the notorious thana culture, but they were used most indiscriminately during the era of the Musharraf government. The present elected government should not show so much enthusiasm in investigations that it breaks the law while in pursuit of those who may not have broken it.
