It’s dangerous to give out advice on cellphones these days.
David Wright has been charged with “Conspiring to Obstruct National Security Investigation.”
David and Ussamah Abdullah Rahim discussed beheading of a particular individual. The conversations took place over a period of time long enough for Ussamah Abdullah Rahim to become impatient. Ussamah Abdullah Rahim decided instead of the beheading, he would shoot some police officers. In a conversation about the new plan, Wright advised Ussamah Abdullah Rahim to destroy his cellphone so evidence on it would be lost. (The conversation was being monitored by the FBI. Ussamah Abdullah Rahim was subsequently killed in an encounter with police officers.)
As I recall, technically speaking, beheading in most jurisdictions is considered to be murder. So Wright and company were engaged in a conspiracy to commit murder long before any discussion of the cellphone.
Law enforcement agencies should not pad their statistics with marginal national security arrests. It devalues any legitimate warning or advice they may have in the future.
