  We consider a hydrodynamic model of flocking-type with all-to-all interaction
kernel in one-space dimension and establish that the global entropy weak
solutions, constructed in [2] to the Cauchy problem for any $BV$ initial data
that has finite total mass confined in a bounded interval and initial density
uniformly positive therein, admit unconditional time-asymptotic flocking
without any further assumptions on the initial data. In addition, we show that
the convergence to a flocking profile occurs exponentially fast.
