After the arrest of Amos Kenan in June 1952 on suspicion of throwing a bomb onto the doorstep of David-Zvi Pinkas, newspaper editorials were lodged against the Canaanite movement and its members. The Coalition claimed to have no connection to Kenan or his act, and both Amir and Ratosh filed a libel suit against Isaiah Bernstein of HaTzofe and Ezriel Carlebach from Maariv on behalf of the Coalition, but the suit was rejected for technical reasons.
