Each barrier includes a first panel at least partially bounding a cavity and a first leg assembly supporting the first panel in an elevated position. A plurality of spikes are removably disposed on the first panel. A flexible snare is disposed within the cavity of the first panel, the snare being secured to the plurality of spikes so that when the spikes are removed from the first panel, the snare is drawn away from the first panel by the spikes. ## Claims ### Claim 1 A barrier system comprising: a first panel at least partially bounding a cavity, the first panel comprising a body having a front face and an opposing back face that extend between an upper end and an opposing lower end, the cavity being formed on the front face of the body; a first leg assembly configured to support the first panel in an elevated position, the first leg assembly comprising at least one leg hingedly mounted to the back face of the body; a plurality of spikes removably disposed on the first panel; and a flexible snare at least partially disposed within the cavity of the first panel, the snare being secured to the plurality of spikes so that when the spikes are removed from the first panel, the snare is drawn away from the first panel by the spikes. ### Claim 2 (depends on 1) The barrier system as recited in claim 1, wherein the upper end of the body terminates at an upper end face and the lower end of the body terminates at a lower end face, the body having a maximum length extending between the upper end face and the lower end face of at least 1 meter. ### Claim 3 (depends on 1) The barrier system as recited in claim 1, wherein the front face and the opposing back face of the body extend between opposing side faces, the body having a maximum width extending between the opposing side faces of at least 0.5 meters. ### Claim 4 (depends on 1) The barrier system as recited in claim 1, wherein the first panel further comprises a foot outwardly projecting from the front face at the lower end. ### Claim 5 (depends on 1) The barrier system as recited in claim 1, wherein the front face of the body is disposed in a plane, the first leg assembly supporting the first panel in an elevated position so that the plane is disposed at an inside angle in a range between 85° and 40° relative to horizontal. ### Claim 6 (depends on 1) The barrier system as recited in claim 1, wherein the at least one leg comprises a pair of legs hingedly mounted to the back face of the body. ### Claim 7 (depends on 6) The barrier system as recited in claim 6, wherein the legs are configured to collapse when a predetermined load is applied to the front face of the body. ### Claim 8 (depends on 1) The barrier system as recited in claim 1, wherein the plurality of spikes are positioned so as to outwardly project from the front face of the body. ### Claim 9 (depends on 1) The barrier system as recited in claim 1, wherein the plurality of spikes are disposed within or adjacent to the cavity of the first panel. ### Claim 10 (depends on 1) The barrier system as recited in claim 1, wherein the plurality of spikes comprise at least 5 spikes. ### Claim 11 (depends on 1) The barrier system as recited in claim 1, further comprising a frangible plate secured to the first panel, the frangible plate at least partially covering the cavity and the plurality of spikes. ### Claim 12 (depends on 11) The barrier system as recited in claim 11, wherein the frangible plate fully covers the plurality of spikes and the snare within the cavity. ### Claim 13 (depends on 11) The barrier system as recited in claim 11, wherein the frangible plate is more frangible and has a lower tensile strength than the body of the first panel. ### Claim 14 (depends on 1) The barrier system as recited in claim 1, further comprising: a second panel at least partially bounding a cavity; a second leg assembly supporting the second panel in an elevated position; a plurality of spikes removably disposed on the second panel; and a flexible snare disposed within the cavity of the second panel, the snare being secured to the plurality of spikes so that when the spikes are removed from the second panel, the snare is drawn away from the second panel by the spikes, wherein the first panel is interlocked with the second panel. ### Claim 15 (depends on 1) The barrier system as recited in claim 1, wherein the snare comprises an elongated piece of netting, fabric, woven material, membrane, or film.
